🛩Ejection seats: Hang on tight, we're going for a ride!

Brought to you by [Quartz Obsession] Ejection seats February 26, 2018 Flying high --------------------------------------------------------------- Earlier this month, a Kenya Air Force F-5 jet crashed. The pilot survived with [only minor injuries]( after ejecting himself from the aircraft and parachuting to the ground—making him the [7,560th person]( who has been saved by a Martin-Baker ejection seat. The Middlesex, England-based company [controls around]( 55% of the ejection-seat market, with more than 17,000 currently in service around the world. (Other big players include UTC Aerospace Systems of Charlotte, North Carolina and NPP Zvedza of Tomilino, Russia.) Unless you’re a military pilot or have an interest in aircraft, it’s unlikely you’ve given the ejection seat much thought. But this marvel of engineering has changed the landscape of military flight in immeasurable ways since its advent around World War II. The Kenyan pilot, and the 7,559 others who have successfully cheated death in a Martin-Baker seat, are eligible for free lifetime membership in the company’s [Ejection Tie Club](.

Let's chat at MWC18 about how technology and ingenuity is transforming every business, every function, every process.[Join the conversation at Mobile World Congress 2018]( Quotable “An ejection seat is kind of a nightmarish, Rube Goldberg-looking machine, and it still astounds me to this day that mine worked the way it did.” — Cmdr. Stanton Parsons, Martin-Baker [ejectee number 4344]( 🐦 [Tweet this card]( Nuts and bolts How does an ejection seat work? --------------------------------------------------------------- Modern ejection seats are powered by explosive charges or rocket motors. Here’s what happens when a pilot pulls the ejection handle: - The cockpit canopy is jettisoned as an explosive cartridge under the seat sends it up an angled guide rail, while a series of restraints tighten around the pilot’s body. - An underseat rocket motor fires, lifting the pilot 200 or so additional feet into the air in order to prevent a collision with the plane’s tail. - A [drogue parachute]( deploys, stabilizing the seat and pilot, who is still strapped in at this stage. - A sensor automatically deploys the pilot’s main parachute, but only at 10,000 feet or below, where the air is breathable. The drogue detaches from the seat. - The seat now detaches from the pilot, whose parachute opens. Once the chute is open, a motor separates seat and pilot, who can now land. If the system is working as it should, this has all has taken place in [less than two seconds](. Ejection seat historian and collector [Kevin Coyne]( says such a complex sequence of events taking place over such a short period of time presents “a level of liability that is unique in the engineering field.” “That one time it has to be used, it has to fire,” Coyne tells Quartz. “The only technology even close to that is airbags, and airbags are a lot less complicated.” So, having ejected from the airplane… what happens next? This [Popular Mechanics explainer]( gets into the details. Industry hazards The not-so-fun facts --------------------------------------------------------------- Let’s be clear: While “ejection seat” [rides]( have turned up in amusement parks in recent years, there’s really nothing fun about ejecting from an actual jet. “Viewed from the perspective that the metal and rivets of the 50,000-pound Phantom must be inspected for structural damage after 9 Gs, there is little wonder that the frailty of human muscle and bones are subject to injury when ejected at forces of 12-14 Gs,” Dr. Guy Clark, a former US Navy flight surgeon and F-4C Phantom crewman, [wrote]( in his 2017 memoir. As a 1991 study published in the Archives of Emergency Medicine [instructed]( “All ejectees should be considered to have a spinal fracture until proven otherwise radiographically.” Other alarming [ejection-related injuries]( include “gross posterior soft tissue disruption,” “upper limb flail injury,” and burns. “It’s a desperation measure just to survive,” Clark tells Quartz. And accidents still happen: Just last month, [Martin-Baker admitted breaching safety law]( over a defective design that killed a pilot in 2011. There’s no doubt ejecting is incredibly risky in the best of circumstances, and only a last resort when catastrophe is imminent—but there are stories with happy endings. “I remember one or two pilots who had ejected two, maybe three times,” Clark says. “They were sent home because the squadron commander thought they’d had enough war, but they did not suffer any spinal injury.” Explainer So, uh... what’s with the tie? --------------------------------------------------------------- As Martin-Baker [explains]( on its website: “The primary objective of the Club is to provide a distinctive tie to be worn with civilian clothing which provides a visible sign of the members’ common bond… All Tie Club memorabilia depicts a red triangle warning sign, the recognised international danger symbol for an ejection seat.” If you are (un)lucky enough to find yourself eligible for membership in Martin-Baker’s club, they’ll invite you to a ceremony in England to present you with your tie. However, you’re not under any obligation to attend. Retired US Navy pilot Charlie Plumb, who ejected in Hanoi and was imprisoned during the Vietnam War, told Quartz: “It was probably 15 years after I was repatriated that I got this letter from Martin-Baker that said, Hey, are you the guy who used our ejection seat? We want to invite you to England and celebrate and give you a tie and a pin to wear and all this stuff. I said, Thank you very much, the seat worked fine, but I don’t have any real plans to be in Europe for a while. Send me the tie. So, there was no pomp and circumstance to me getting the tie; I got it in the mail.” USMC fighter pilot [Errett “EJ” Bozarth]( ejected from an F-4J Phantom II on January 3, 1976, and has several friends in the Ejection Tie Club including six other members from his squadron. When Bozarth’s original tie wore out, Martin-Baker sent him a replacement, he told Quartz. Person of interest The first lady --------------------------------------------------------------- The first female aviator inducted into the Martin-Baker Ejection Tie Club was Lt. Linda Maloney, [ejectee number 4346]( a US Navy flight officer who punched her way out of a Grumman EA-6A “Electric Intruder” during a training run on February 11, 1991. Instead of a tie, Martin-Baker gave her a silver necklace with a little ejection seat hanging from it. Cmdr. Stanton Parsons, Martin-Baker [ejectee number 4344]( was at the controls of Maloney’s aircraft that day. “The airplane was radically out of control and it was all I could do to pull the handle to get out of it,” they told us. “We went into the ocean; we ended up about ten miles apart, we were rescued by two different helicopters. We were in the water for about an hour. It was freezing cold; each of us had a pretty good case of hypothermia going.” Parsons also got a tie, but doesn’t wear it. (His wife framed it.)

Million-dollar question How much does an ejection seat cost? --------------------------------------------------------------- A new Martin-Baker ejection seat runs in the neighborhood of [$140,000-$420,000](. A usable UTC Aerospace [ACES II]( ejection seat—which has been installed (and replaced by the ACES 5) in the A-10, F-15, F-16, F-22, B-1, and B-2—runs somewhere in the quarter-million dollar range. Much of the cost of an operational seat comes from the explosive charges used to propel it into the air, according to Kevin Coyne, who has eight ejection seats in his collection, in various states of repair. Minus the explosives, which must be replaced every 10 years, “the basic seat is probably about $60,000,” he says. Purely decorative units for use as desk chairs or home furnishings are slightly more affordable, with a decommissioned Martin-Baker seat going for [$19,500](. (“Not for Flight Use,” says the listing.) “If someone has restored a seat, it should not have any active cartridges on it, but even so, a seat should be treated like a firearm,” Coyne [cautions]( on his website. “If you don’t know the situation, treat it as if it were loaded.” poll Have you ever parachuted out of a plane?
