Michael's Dispatches
The Kopp-Etchells Effect
- Details
- Published: Monday, 17 August 2009 03:20
A CH-47 helicopter whirls in with a “sling load” of resupplies from Camp Bastion to FOB Jackson in Sangin.
The pilot comes in fast, to the dark landing zone, lighted only by “Cyalumes,” which Americans call “Chemlights.” The sensitive camera and finely engineered glass make the dark landing zone appear far lighter. The apparent brightness of the small Cyalumes provides reference.
A show begins as the helicopter descends under its halo.
The charged helicopter descends into its own dust storm.
Gently releasing the sling load.
The pilot hovers away from the load, pivots and begins to land.
The dust storm ripples and flaps over the medical tents.
Heat causes the engines to glow orange.
Dust begins to clear even before landing. The helicopter, under its own halo, casts a moon shadow.
The halo often disappears when the helicopter ramp touches the ground. Again, the conditions are quite dark, but the excellent camera gear has tiger vision.
The British medical staff treats many wounded Afghans who often show up at the gate. In the photo above, Dr. Rhiannon Dart (right) observes as an Afghan patient is medically evacuated to the trauma center at Camp Bastion. The medics and Dr. Dart are especially respected for the risks they equally share here. The medical staff walks into combat just like the other soldiers—frequently side by side in close combat. Numerous times per week, their battlefield work, often under intense pressure in hot and filthy conditions, is the deciding factor on whether soldiers or civilians survive or die. I asked Dr. Dart if Afghan men have any reservations when being treated by a woman. She answered that when men are seriously wounded—which is about the only time she sees Afghans as patients—they don’t care if she is a man or a woman. During a mission last week, I saw an Afghan soldier walk by with a bandage on his hand. Dr. Dart stopped the soldier, asking him to remove the bandage. Contrary to harboring reservations, the soldier appeared relieved that she wanted—actually sort of politely demanded—to examine his injury.
The ramp lifts in preparation for takeoff and the halo begins to rematerialize before the helicopter lifts into the darkness and disappears. Soldiers call the medevac flights to Camp Bastion, “Nightingales” or “Nightingale flights.” Shortly after sunrise on the morning of 13 August, an element from this unit was ambushed nearby, killing three and wounding two others. Despite the immediate danger, the helicopter came straight onto the battlefield. After the initial ambush, and another successful ambush during the evacuation, the British soldiers did not return to base but continued with the mission. Later that evening they were twice ambushed again, sustaining more fatalities as two interpreters were killed. Soldiers asked me to go on that mission but I was busy assembling this dispatch. One of the killed soldiers, shortly before the mission, had looked over my shoulder as I selected the photos. Captain Mark Hale was killed while aiding a wounded soldier. Mark had particularly liked the next three images:
Night after night, helicopters keep coming. Last month a civilian resupply helicopter had tried to land at this exact spot but was shot down on final approach. Two children on the ground and all persons aboard were killed. The helicopter crews earn much respect.
Sometimes the halos appear like distant galaxies.
In motion, the halos spark, glitter and veritably crackle, but in still photos the halos appear more like intricate orbital bands.
Perhaps like the rings of Saturn.
The halos usually disappear as the rotors change pitch, dust diminishes and the ramp touches the ground. On some nights, on this very same landing zone, no halos form.
On another night, the helicopters return. The camera is jostled, accidentally creating a double image.
They keep coming.
What is this halo phenomenon called? None of the American or British helicopter pilots seemed to have a name for the effect. They provide only descriptions and circumscriptions. I asked many people, and finally reached out to Command Sergeant Major Jeff Mellinger (one of my “break glass only if” sources whom I ask when other means have failed). Jeff asked pilots, and came back with an excellent description from one pilot:
"Basically it is a result of static electricity created by friction as materials of dissimilar material strike against each other. In this case titanium/nickel blades moving through the air and dust. It occurs on the ground as well, but you don't usually see it as much unless the aircraft is landing or taking off. The most common time is when fuel is being pumped. When large tankers are being fueled they must be grounded to prevent static electricity from discharging and creating explosions."
But still no name. How can the helicopter halos, so majestic and indeed dangerous at times, be devoid of a fitting name?
A phenomenon in need of a name. Mark Hale had liked this image and the next.
I spent two weeks searching for a fitting handle but all attempts came to naught.
The halos are different every night. Some nights they are intense, other nights dim, but often there are no halos.
There are explosions and fighting every day and night.
Under the moon.
This time exposure shows where the pilot briefly hovered before dropping in.
Our casualties in this war reached an all-time peak in July 2009 and the heaviest fighting was here in Helmand Province. On 10 July, elsewhere in Helmand, some of America’s finest soldiers were hunting down Taliban.
Members of the U.S. 3rd Battalion, 75th Ranger Regiment closed space with the enemy, apparently killing at least ten. Corporal Benjamin Kopp was shot and evacuated to Germany, then back to the United States, where he died just over a week later on 18 July. Benjamin was 21 years old and at the very tip of the spear. If not for such men, we would be at the mercy of every demon.
Benjamin Kopp and his comrades were delivering the latest bad news to the sort of people who harbored the terrorists who attack innocent people around the world every day, and who attacked us at home on 9/11. Ranger Kopp was a veteran with three combat tours. He knew the risks, yet continued to fight.
Benjamin was laid to rest at Arlington National Cemetery. Secretary of Defense Robert Gates quietly attended the funeral, as did my good friend, Colonel Erik Kurilla, the new commander of Ranger Regiment, where Kopp served until America lost one of its finest Sons.
Yet the effect of Corporal Kopp did not end on the battlefields of Afghanistan; he only regrouped and continued to serve. Corporal Kopp had volunteered as an organ donor and his heart was transplanted. Two days after most people would have died, Benjamin Kopp’s heart was transplanted into Judy Meikle. According to the Washington Post, Meikle said, "How can you have a better heart?" said a grateful Judy Meikle, 57, of Winnetka, Ill., who is still recovering from the surgery. "I have the heart of a 21-year-old Army Ranger war hero beating in me."
Other organs were also donated for other recipients.
Benjamin Kopp’s case is reminiscent of so many others whose names are and faces will forever remain unfamiliar to most of us. The Angels Among Us are nearly always invisible to our eyes until it’s too late to say “thank you,” and “farewell.”
On August 11, I attended a small ceremony for a British soldier from this base in Helmand who was killed in combat the day after Benjamin passed. His name was Joseph Etchells. I was told how Joseph died in a bomb ambush, and that his last request was to be cremated, loaded into a firework, and launched over the park where he used to play as a kid. When Joseph’s last request was explained, I burst out laughing and the British soldier who told me also was laughing. The absurd humor of Joseph’s request was familiar, and it was as though Joseph were standing there with us, laughing away.
Lieutenant Alan Williamson was “Joey’s” platoon commander here in Sangin. LT Williams said that the other soldiers called him “Etch,” or Joey, and that Etch was born in 1987. He joined the army at age 16, though he could not deploy for combat until he was 18. Etch did a tour in Northern Ireland and three tours in Afghanistan, including 2006 in Now Zad where he endured 107 days of straight combat wherein they fought literally every day. In 2007 Etch deployed to Kabul and then performed “Public Duty” by guarding the Queen outside the palaces.
Lt Williams said that Etch was a, “Young and very keen Section Commander. Most Section Commanders like to be a few men back so they can command without being in immediate danger, but “Etch” refused to be that far back, and was always right behind the [“point man.] He was an outstanding runner. He left his fiancé behind. He would have been a very young sergeant. He was an outstanding, outstanding soldier.”
Joseph Etchells and Benjamin Kopp were both Corporals in different armies. Both had served three combat tours. Ben was 21, Etch was 22, and they both fought their last battles in Helmand Province. The names of these British and American warriors are listed consecutively in a roster chronicling our sacrifices in Afghanistan.
Last month there had been a large service here for Etch, but I witnessed a much smaller service where those closer to him came together to pay final respects. This service in Sangin occurred on the same day that a final ceremony was being held back in the United Kingdom. About twenty soldiers attended. The event was quiet and respectful and I wanted to be back in the United Kingdom to salute the rocket launch as it carried away the payload of Joey’s ashes, and exploded over the park. Here in Sangin, the bugler played and his buddies tossed their cap feathers into the Helmand River. The red and white feathers drifted away in the same waters where Etch used to swim after missions, down into the desert. Here they call it the “Dashti Margo,” the Desert of Death.
And so a fitting name had arrived to describe the halo glow we sometimes see in Helmand Province: Kopp-Etchells Effect, for two veteran warriors who died here in Helmand, Ben on the 18th, Joe on the 19th of July in the year 2009. It’s not hard to imagine the two Corporals have already linked up and regrouped, and in sense they have. Knowing combat soldiers, it’s easy to imagine them laughing away at the idea.
The Kopp-Etchells eponym can be seen as a cynosure for the many who have gone before the Corporals, and those who will follow. I had talked to Captain Mark Hale nearly every day for two weeks. Mark liked the name. And then Mark himself was lost on Thursday along with Daniel Wild as they were aiding a wounded Matthew Hatton. I heard very good things about Daniel Wild. They say he was a good and tough soldier. I’d seen Matthew Hatton on the battlefield and felt more confident by his presence. Hatton was a well-respected man. As for Mark Hale, I only knew him for two weeks. Mark will be missed by many people, myself included.
The war goes on and all the fallen soldiers know what we must do. We must keep moving. There will be time in the future to pay proper respects, and to reflect upon their honor. Now is not that time.
While waiting for a helicopter to land, there was activity on the perimeter, and then an unseen hand fired a flare so that we could see who was out there.

I was curious if you had a chance to read this http://www.facebook.com/ext/share.php?sid=118227974092&h=7I-cM&u=msoAM and if so, what you think of the article... it's pretty benign but I was curious as to it's accuracy.
http://en.wikipedia.org/wiki/Kopp-Etchells_effect
Well done and a great idea for memorialising these guys.
Keep up the good work.
Thank you for another heartfelt post. Your writing enables us to be right there with you (almost) as our emotions build while your words tear through our eyes. Your compassion for your fellow brothers in arms is inspiring and your reporting is spot on. Again, many thanks for your strong work. Be safe.
Randall
Please keep in mind that, should you ever make that list, many hundreds who depend on your eyes, ears, and camera will have no way of knowing what is really going on there.
There are some cold ones waiting ... make sure you collect, please.
Today though coalition soldiers will continue to walk or drive out of the gates and show determination to ensure that the fallen did not fall in vain.
David
I will be attending Lance Corporal Javier Olvera's funeral tomorrow.
Stay safe...God Speed.
P.K. Fields
ive only been getting your posts for about 2 wks. i dont even know where i got the link. this post was quite sobering and im writing through tears for the men and women who have given their lives selflessly. may God be with their families in their loss. thanks for doing what you do.
god bless you too.
Michael, anychance you can place just ONE picture of the effect in the public domain? We need to add a picture to Wikipedia, and can't if you copyright it?
From the sister of Capt. Charles F. "Chic" Burlingame, III, pilot of American Airlines flt 77, Pentagon attack, Sept. 1, 2001
Thank you for this sympathetic treatment of the lives and deaths of so many brave service personnel (and the excellent photographs).
It is heartening in a way to know that even in this world there are still those with the courage to step forwards and tackle a most difficult job on behalf of nations whose populations often cannot be bothered to give them a thought.
Your conribution remains a vital component of getting some perspective of what it going and how we are doing.Certainly if I relied on the UK MOD I would remain in the dark. It is also important that our guys realise that many of us care very deeply about their fate, even if all we can do is write irate letters to disinterested parliamentarian s (with the notable exception of Lady Anne Winterton).
Keep your head down, regards Barry Sheridan

Thank you all for your service and sacrifice.
Thank you for the telling the stories of these heroes and photographing their work. It really puts a face on a war that if too often forgotten here at home.
May God bless you and all of our brave soldiers.
You seem to be living a life that was meant to endure and report the news from the battle front. Otherwise, you could have been on tht fateful mission, when so many were lost. Some posts have said that the west doesn't care what's going on in Afghan, but Ican tell you, the silent majority in the USA DOES INDEED CARE, more than they will ever know. Americans know that freedom is never free and our fighting men and women and their coalition of brave soldiers will never let that be taken from us.
It's true that politicians at home have done their best to obscure what's going on in Afghan, with the health care debacle, home foreclosures, bank and auto industry bailouts, but we know our young men and women of our country and the coalition countries are fighting for their VERY LIVES and could care less about those things, but will fight to their deaths to preserve the right of those at home to dworry about those things!
Tell the Brits and other coalition partners that we shed our tears for their losses, just like they were our own, as they give their lives along side our troops. All for one and One for ALL! Save travels Michael!
So in this hamlet in southern Afghanistan, a village of adobe homes surrounded by fields of corn, the local people will stay home when much of the rest of the country goes to the polls on Thursday to choose a president.
"We can't vote. Everybody knows it," said Hakmatullah, a farmer who, like many Afghans, has only one name. "We are farmers, and we cannot do a thing against the Taliban."

Throughout their lives they tried,
To fight for the way of the cause.
In honorable ways they died,
Yet we could not give pause.
Now that the fight is done,
Those that we cherish are safe.
Our friends are gone...
Did they seal their fate,
So that we may endure,
The things they held so dear?
After all this time,
We must try and make amends.
Now is the time,
To honor our fallen friends.

I was struck by your dispatch; the very first name that appears on your list, Sgt Bill Cahir, fell last week in Afghanistan. He was a member of 4th CAG and a 40 year old Marine Sgt. His brother was a classmate of mine at State College High School and Bill and I are alumni of Penn State University. Bill is the third soldier of the sea from PSU to die in combat since 9/11; the first two were Lt. Michael Murphy USN/SEAL and Captain Todd Seibert, USMC.
Bill left journalism after 9/11 to enlist in the Marine Corps at 34. He deployed to Iraq, fought in Fallujah and ran unsucessfully in the most recent PA Democrat primary in Pennsylvania. He was on his 3rd combat tour and left behind a wife pregnant with twins. He will be laid to rest at Arlington sometime next week.
Thanks for everything that you do.
Semper Fidelis.
Re: Helicopter Halo - you could call it the Hale Effect?
You might also want to post a couple of the clearer shots of the Chinook on Airliners.net, an aviation photography site that is widely viewed by aviation enthusiasts and a great way to help get the name into common usage.
Stay safe.
And thank you Michael, for your travels in harm's way to provide us with a truthful and sobering view of this current conflagration. Please convey my thanks and prayers to them all, and that they safely return in glory.
Everyone who reads this needs to spread the word by email and by telling of Michael's Quest and Chronicles.
Also everyone needs to remember that no one except his readers are supporting him. Everyone needs to encourage donations to Michael. I have not been able to give much through the years to Michael, but I have always considered it money well spent.
I have two grandsons now in the Military, and one more chomping at the bit to become a United States Marine. So far my two who are serving are serving out of actual combat but that can change at any time and they stand ready to go.
As previously stated, the vast majority of the world doesn't care about the wars or those that fight in them, even though without these men and women, sons and daughters, grandsons and granddaughters the world would be a very terrible place for all of them...and us.
So, make it your personal responsibility to get the word out and help Michael tell his stories and present his pictures to the world.
You know it is the right thing to do.

I have gotten your notes from a friend for a long time. I just wanted to tell you how much an old marine and Army guy respects your efforts. I will do what I can to continue to support our troops and our country and your efforts.
Thanks
I bet your posts and pictures short out A LOT of keyboards.
The copter pics are truly amazing, and the second to last especially so. You can almost see the cap and flowers left behind by the warrior heros.
Maybe that's why they call them halo-copters.
Stay safe, and keep shooting and posting.
Kim and I spent time with Ben's family in the days before his mother made the decision to give him away. You will travel a very long distance and time to find another human being so full of love, life and grace as Jill. I was unable to attend the funeral at Arlington (was in Saudi Arabia), but Kim was there. Thanks for acknowedging CPL Kopp in the same way oyu do so many others.

Our Father was a founding member of the American Heliicopter society and was instrumental in founding the first two attack helicopter squadrons in Korea. he worked for Sikorski, then NASA(when it was NACA) handling the initial research on rotor tips going supersonic in a dive. He then worked with Frank Piaseki as military liiason (Frank was my godfather) then for many years with Charles Kaman. When he finally retired from active reserves his mobilization billet was to take over as pres of the Naval War College. He passed on in June of 2008.

Thank you for pointing out that when it comes to the dirty work for country, for NATO , where ever we are sent Often Marines and Navy are the closest of brothers. I owe my life to a couple of marines and a couple of them owe me but we neveer look at it that way. We just find a way no matter what to bring our own home. I can't carry two Boston phone books very far anymore but I can still swim deep and far.
Thanks for the rememberance of our unity.

I will be starting a new job soon, my first since being unemployed for the past 23 months. I promise you a cut from my first paycheck. Thank you again.
Stay safe Mr. Yon and keep up the good work.
Stay safe Michael.
I live in Irvine, California where a grass roots group of citizens spontaneously crafted handmade memorial crosses in 2003 to honor the fallen Americans in Afghanistan and Iraq. For six years the number of crosses each bearing photographs, names, ranks, age, hometown and cause of death of the fallen heroes has increased. Each year my family and I attended the Memorial Day service to pay our respects; this year we decided to participate in the daily services from Memorial Day through July 5th.
Each night a different group of people stopped by and helped replace and light 150 candles, one for each memorial. We had local citizens, but others came from several states and a handful of countries to pay their respects. It was common to see a veteran of the war on terror stop and quietly sit in front of a memorial and then leave. I can honestly say that it was among the most moving experiences of my life, to see the faces of all the fallen and hear their stories and honor them with the pledge of allegiance, a prayer and taps.
The group of citizens is now working to create a permanent memorial on the same site that will have all the names etched in granite panels displayed in a beautiful setting. We hope to have it completed by next May. To read more about this effort go to www.northwoodmemorial.com and view the video about how it all started.
If you wish to honor the fallen in your town, just do it. It doesn't require the government's permission or money, just gather a group of like minded neighbors and do it. Trust me you'll meet new friends and feel better for the effort. The testimonies of gratitude from the local Gold Star Families for remembering their children/siblin gs/parents will move you to tears.
Here is his hypothesis:
Hi Cathi,
While it's useful to add additional nomenclature for a specific effect (e.g., Kopp-Etchells Effect for rotating helicopter blades in dust), it doesn't lead us to a complete explanation. These are amazing pictures, but I thought about a different effect given the nature of the sand crystals in the dust.
Airplanes often accumulate electrostatic charge due to friction (triboelectric effect) as they move through the air or even due to static charge separated and accumulated by the air itself from rapid movement of wind (consider the spark that set off the fire in the Hindenburg disaster). This charge is usually dissipated at the sharpest points of the object where the electric fields are naturally highest (this is one reason we use lightning rods - sharp points to spray excess charge into the air). Most aircraft have such electrostatic charge dissipators built into their designs. If there were a buildup of charge beyond what the charge dissipation devices could handle then we would see sparks occurring from the tips of wings (or helicopter blades) as a coronal discharge or even a complete spark. It would look like miniature lightning or electrostatic glowing at the sharpest tips, but on the helicopter blade edges and tips.
But these pictures seem to show a different effect. If you look closely, the glowing is not coming from the metal blades but from the dust itself. It exists in the dust AFTER the blade has passed. This would seem to suggest more of a piezo-electric effect. The piezo-electric effect occurs because crystals such as quartz (e.g., as found in sand and sand dust) are compressed from some kind of rapid impact (like being hit by a rapidly rotating helicopter blade) and cause excess electrostatic fields on the surface of each crystal, often thousands of volts, that can discharge right on the crystal. Piezo-electric crystals are today used in charcoal grill lighters and on most gas stove lighters. When you use a charcoal grill lighter you pull a trigger that slams an internal hammer against a crystal at the end of the lighter where a spark is generated to light the fumes coming from charcoal lighter fluid.
From a blog in 2003:
"Those aircraft are hovering, and those flashes of light are the sand particles emitting bright glows as they are disturbed. It is the piezoelectric effect, where a crystal makes a big energy shift when its crystal lattice is mechanically disturbed. This is the way a diamond record needle drives the sound into the amplifier. The goggles amplify about 40,000 times, so these very dim glows look like sparks. As an experiment, get fully dark adapted, then smash a sugar cube with a hammer. The glow is a shocking green!" (NickLappos, 27th April 2003, 05:25)
The blog continued with one person suggesting that the effect may be caused by burning bits of metal being emitted by the helicopter blades like grinding metal from a high speed sander. But I think that those bits of metal would be thrown off the wings outward. These glowing particles seem to stay in place as the blade passes.

If you are interested, I'll let you know if a student does take him up on this and what the results are.
Thank you for all you do, Michael!
Mind you the loss of lives of Western World people seems to sensless considiering it will go back to Talibin, War Lords to Tribes.
Regarding the CH-46 to CH-47 in Canada we call them Schnook choppers & have been the best ever. Fact is we have a lot more Ch-47 with some modifications on order here in Canada.
I've read your blogs on and off for several years now. Your reporting has without a doubt been some of the most interesting and worthwhile coming out of the middle east. Thank you for the work you do. It's amazing and I'm sure, quite thankless.
I just enlisted with the US Army as an 11X. I'll be shipping to BCT at the end of october. Ideally, my name will never show on the list of deceased, but if it does, I'd want you to report it. Nobody else comes even close to doing justice to those that have made the ultimate sacrifice.
Benjamin was from right here in Minnesota, I believe Rosemount, south of St. Paul. His funeral was huge. He had it at the same funeral home my wife had hers at, about 2 weeks later. I had no idea about the transplant though, it was not mentioned in the papers. My own son has volunteered to donate his organs upon death. It sort of shocked me. Heroes!!
I remember hearing it called St. Elmo's Fire and also the piezoelectric effect but am fully behind the fitting name change proposed by you. To suggest a respectful and memorializing name to a building, a park, or in this case a common yet largely unknown effect is honorable. Thank you. And to all those who are spending many days of their lives fighting, and sometimes dying for the freedoms, dignity and lives of others, THANK YOU.
The effect seen is very probably from little bits of quartz crystals in the dust getting hit by the rotor blades. When piezoelectric crystals deform they release very high voltage jolts of electricity. Piezoelectric quartz is very common.
Michael yon is an incredible human being. I wish I had the nads to go where he goes. Keep the picture sharp on our boys & girls Michael, we are buoyed up by your reports, even as we grieve for the losses.
We just want to thank you for this wonderful halo effect that has been created and named after Joey, we miss him so much, when we are on a low we look at this page and it puts a smile on our face.
Joey will be missed everyday forever.
Thank you
Love

Perhaps some business owners who read his posts would sponsor his efforts for a Public TV type plug i.e. "This post made possible by support from: Acme Widget & Gadgets, Smalltown, Anystate. Any takers? We need more Michael Yons and fewer NY Times reporters.
Kudos to you, Michael, and to the patriots you write about and photograph.
Keep safe.
Whenever I see a TV report of returning Soldiers who are carried with great ceremony through the village of Wotton Bassett, I am reduced to tears at the thought of the trauma the families of those Soldiers are being put through
1000000 votes are not worth the life of one Soldier, from whatever Country, thank you Michael for your accurate and unbiased reports and stories and pictures regarding ALL the brave young Soldiers from all countries out there in the Afghan conflict.

Anyway , I wish that your sons and daughters return home safe , and to have good lives. That they don't have to shot to anybody , and that nobody have to shot them . War is Hell on Earth , I know that much.

Regardless, from today on, it's the Kopp-Etchells effect. As an aside, you haven't lived until you've seen a baby Second Lieutenant decide things aren't moving fast enough during a sling load operation and grab the hook with a bare hand. A secondary presentation of the Kopp-Etchells effect can be seen when the young officer's eyes go wide, his hair stands up and he makes a sound something like, "SHEEIIIGGGGGUU UBBBBBBUUUUBBBB UUUUUUBBBBB!" It keeps happening and it's never going to get old.
New year is coming up and I'm going to launch a few rockets for Etch and Koop. They and the others on the list have gone into my memorial and get a shot lifted when ever I get a chance.
Thank you, Michael
Keep it simple. Works for me.
Simplistic? Who cares?
Michael, you have my respect, sir. I'm a civilian, not tested under fire and you hold the job I'd dream of having.
I'm just not worthy.
Cheers.
There are a lot of us who ARE grateful to you ALL.
Your photos are a strong testament to them.
Stay safe and may God bless you.
But it's "Saviour of 'is country" when the guns begin to shoot;
An' it's Tommy this, an' Tommy that, an' anything you please;
An' Tommy ain't a bloomin' fool -- you bet that Tommy sees!..." Rudyard Kipling
I salute all those that serve. GLS, Col USAR Ret.
I pray that dear God don't let the generals and politicians stuff up another war through lack of resolve and lack of support for these brave people.
The photos are extremely good, and could serve as textbook examples.
Someone mentioned Titanium-nickel as a participant in the transaction--"I n my day" the rotors were more likely Sitka spruce.l
Congrats to the photog--and best of luck to those who must fly the aircraft in what must be rather nasty conditions.,

I'd be curious to know what the engine mechanics have to clean out of the hot sections in the turbines, as this stuff often melts to glass there.
The phenomena isn't St. Elmo's fire - that will accumulate at discharge points etc. (pitot tubes and the like) as well as rotor blades. This phenomenon has been noted among helo pilots for some time and speculation has it as some kind of piezoelectric discharge (caused by impact with the quartz sand) that mimics the von Guericke effect by creating static discharge from the quartz structure that's carried into the airframe. The sparkling effect is primarily from the static discharge wicks at the rotor tips. In other operational areas, this has been noted in operations over high-quartz sand and concrete which gives anecdotal support to the piezoelectric theory.

Triboluminescence is likely a byproduct of piezoelectricit y, and the differences don't matter here since the article was really about the loss of fine young men set against the fireworks of sand and motion.
Please could you correct this.

*** The most common time is when fuel is being pumped.***
When large tankers are being fueled they must be grounded to prevent static electricity from discharging and creating explosions.""
Static electricity is not a function of friction, (friction is mechanical) it is a result of proximity of electrical charges in insulators. Static electricity is built up even when there is no friction between bodies, it is an electrostatic effect (Coloumbs experiments). The fact that the effect is seen consistently when the chopper is grounded to the Earth proves the energy for the luminious discharge is from the ground, not the blades. The blades are stirring up relative motion of sand against the ground, separated by several feet of chopper, that motion can generate massive charges. The lower part of the chopper is a giant electrical conductor to bridge the gap between the sand layer and the ground.
A crude electrical analogy is a capacitor, electrical energy stored in an insulator between two conductive plates, except a capacitor stores free electrons in/from conductors, and static is a pheonomenon in electrical insulators.
Light is photon emission when an atom's electron changes state from high to low. The eletrical energy is apparently from the ground, up (or down) through the choppers metal parts, through the blades (Ti is a conductor) and discharging against the sand cloud. The chopper conducts excess charge to the blade tip/edge where it arcs over to the swirling sand, with a light discharge.
Piezoelectric effect would not take into account the fact that the effect is much more pronounced when the craft is grounded. It is purely within the (crystallaine structure) when mechanically distorted.

On a much lighter note, when I served in the 2/505PIR, we used to sling load HMMWV's with Chinooks. It was a ritual of sorts to have the new guy (myself included) hook the sling to the helicopter while a more veteran soldier was supposed to ground it first.... supposed to. Looking back, I can't believe we'd send that kind of voltage through a kid as a joke - although it still makes me chuckle to see a guy get thrown from the top of a HMMWV because his "buddy" didn't ground the hook.
Philip Graham Etchells
The reason it is not seen on the ground is the craft is "grounded" better than when in the sky.
Keep up the good work!
The only viable solution is to coat the titanium.
You truly are the word man. Thank You for sharing. GBU ALL THE WAY SIR AND THEN SOME
