Plane passenger accidentally activates ejector seat

Recommended Posts

:o Langebaan is 100km from where I stay!

See the reporter got details wrong, just as they do in skydiving reports - the PC7 is a turbo prop, not a jet :P



They also said the passenger "inadvertantly" ejected.
I bet he was curious.:D

Since it ended "well" this is just hillarious :D:D:D:D

"It is thought he activated the ejector seat after lurching forward during an aerobatic manoeuvre and accidentally pulling on the black and yellow emergency handle between his legs."

That is pure slapstick. :D

It's almost as bad as accidentally resetting the 'wings stay on/ wings fall off' switch.

I'd log that in my book, for sure.

Here's some info on the A/C:

This part was interesting:

The novice flier instantly shot through the jet's perspex canopy and was blasted 100 metres into the sky by the rocket-powered emergency chair.



:oB|


I, too, wonder if that's accurate. Doesn't pulling the handle not just eject the seat, but actually commence the ejection sequence -which begins with the jettisoning of the canopy? (I don't know re: this particular system, and I'm not going to look it up.) If not - ouchie!.

This also begs the question: during his pre-flight briefing (if any), wasn't he told "Don't pull this handle"?

Out of wikipedia:
Aircraft designed for low-level use sometimes have ejection seats which fire through the canopy, as waiting for the canopy to be ejected is too slow. Many aircraft types (e.g., the BAe Hawk and the Harrier line of aircraft) use Canopy Destruct systems, which have an explosive cord (MDC - Miniature Detonation Cord or FLSC - Flexible Linear Shaped Charge) embedded within the acrylic plastic of the canopy. The MDC is initiated when the eject handle is pulled, and shatters the canopy over the seat a few milliseconds before the seat is launched.

Through-Canopy Penetration is similar to Canopy Destruct, but a sharp spike on the top of the seat, known as the "shell tooth," strikes the underside of the canopy and shatters it. The A-10 Thunderbolt II is equipped with canopy breakers on either side of its headrest in the event that the canopy fails to jettison. In ground emergencies, a ground crewman or pilot can use a breaker knife attached to the inside of the canopy to shatter the transparency. The A-6 Intruder and EA-6 Prowler seats are capable of ejecting through the canopy, with canopy jettison a separate option if there is enough time.

CD and TCP systems cannot be used with canopies made of flexible materials, such as the Lexan polycarbonate canopy used on the F-16.


I'm not sure what the PC-7 has, but "thru the canopy" is not unheard of.

Detonation cord is visible here:

The F-16 is interesting in that the pilot does not activate the ejection seat; He activates the canopy ejection.
The canopy lifts off with the aid of a pair of rocket motors in the two forward corners of the frame.
The canopy lifts, pivoting on the mechanism at the rear, and as it approaches 90 degrees, a lanyard is pulled,
activating the ejection seats.
At full 90 degrees, the canopy detaches from the a/c.

BTW the F-16 transparency is a sandwich of 3/4" Lexan on the inside with 1/4" Plexiglas on the outside.
I really wouldn't want to be shot through it.B|

Many canopies have explosive charges rigged to them in order to shatter the canopy instead of jettisoning them.

The RS211, Harrier Variants, some others that don't come to mind this min.

The idea is that a very low flying high speed aircraft can get you out faster that way.

oops I just read that John already responded.

I've known 3 guys who have made 4 ejections. Only one claimed to have enjoyed it in the least. It's a rough ride.:S:D



I used to think it would be a cool ride...until I read the specs for what USAF considered an acceptable rate of spinal compression injuries, (while I was in Escape Systems Design at General Dynamics).[:/]

In his autobiography "Baa Baa Blacksheep", Pappy Boyington writes about bailing out of his burning Corsair at low altitude after being shot down. He said that he put his feet on the stick, grabbed the ripcord with one hand, undid his seat belt with the other hand, and kicked the stick forward. The negative G's threw him out of the burning plane. He said that if he had a third hand, he would have opened the canopy first.:o He launched himself right through the bubble canopy and got pretty well lacerated.
