Eglin F-35 crash

During the ejection sequence the “transparency removal system”/det cord embedded in the canopy fires to create a hole for the seat to go through. As the Elgin pilot found out, apparently this sends shards of plexiglass and whatever metal coatings are on the canopy both inside and outside the jet. If you’re wearing the issued flight suit and vest option (instead of the flight jacket), it sounds like this metal ends up going through the sleeves into the pilot’s skin 

Is this the result of the backwards-ass canopy and more fallout from the POS B model compromises?

[brabus 1,580]

Yep. No hyperbole - the B model is at fault for the majority of design flaws. That’s a nearly universal belief amongst pilots of all services. Even worse is the USMC has no real operational need for the F-35 (it did need new aircraft, but there were better choices), and the primary role of USMC air is CAS; it’s no secret the F-35 is not the best choice for that mission set (assuming low threat stuff the USMC would actually find itself in while only having organic air available).

We should have built one model for AF/Navy (call it the C...DGAF about the A’s 9g capes) and the USMC should have purchased super hornets. We’d all be so much better off.

It probably wouldn't have been as bad were it not for the obsession of Marines = VTOL.  Have they ever actually used that capability in a forward-deployed environment? (Not the ship, but a place that requires landing and taking off where there are no runways on land).

Outside of taxing in the C, it's the best variant. More gas and bigger wings make such a large difference. 

Biggest issue is having three variants with multiple services and partner nations all pushing for different things.

It's too bad so many recent aircraft have opted for det cord 6 inches from your cranium as a means of egress (T-6, F-35, T-7). 

[MIDN 3]

Does anyone know if people have been hurt by the canopy det cord from ejecting from the T-6 or T-45? 

[brabus 1,580]

Det cord - Another example of no pilot input into the design process. Yeah sure, even though there’s a plethora of ejection success without Det cord, I totally would rather have an explosion 3” from my nugget and eject through shards of glass and flying metal as a result of said explosion.

[BashiChuni 1,056]

How is that different from the t-6 det cord?

Being so weapons limited, I’d argue that the internal gun is damn near mandatory.., despite our gun chine problems and the questions about the accuracy of the HMD symbology... and don’t hit me with “external 9’s”... although the sidekick option is compelling.

so.. give me more thrust to weight (like.. a lot more)..and then the larger wing of the 35C... that way I can actually get out of trouble and execute some real L&L tactics if need be as opposed to being more reliant on the magic pants....I’d take a slight hit on gas for that... as I’m often running around with a ton of fuel and no amraams left during a DCA.  

Lots of nuances to this discussion I haven’t even touched on.. a bit of thread drift too.

I’ve talked to a guy who ejected out of the T-6 a few years ago who also had the det cord explosives in the canopy basically turn it into a grenade going off right next to his body. Said he was filled will glass that he could feel underneath his skin for months. I don’t understand why it’s the new hotness in ejection seat design. Even if you actually fly with all your shit rolled down (which almost no one does) it still messes up the pilot when they have an explosive embedded in glass go off a foot away from them. 

[SocialD 1,031]

If only we hadn't already learned our lesson about building one airplane for all services, then having to phix all of its phucking deficiencies.  Is it to late to name it the Phantom III?

Had bad wreck in high school   Lots of windshield in knee and arm joints.  You could feel it in there most days and then just randomly sitting around you'd look down and see a piece breaking the skin and would pop out.

That boat anchor fuselage is a result of the B model.  I had the opportunity to see the engine with it's gearbox that connects to the driveshaft that connects to and turns the lift fan and it's one ungainly large piece of machinery that has to be stuffed into the fuselage.  And that didn't include the actuators and crap for the lift fan doors.  RAND did a study and said building 3 separate aircraft would have been cheaper.

I don’t need a rand study to tell me that.... and I’m willing to bet the three separate aircraft would have each been better, too....

I know a couple people that ejected from T-45’s... none directly complained about that to me.

lots of folks have ejected from harriers, with no issue with the Det cord.

the F-35 TRS Det cord is probably “improved”.. the pilot from the Eglin mishap did say he had tin shards embedded in his skin... so there’s that.

For those of you in aircraft with det cord in the canopy:  is there any talk... officially or unofficially... that when you are in a controlled ejection, you jettison the canopy manually, and THEN pull the ejection ring?

In the T-6 as a stud so my knowledge is inherently limited, but there’s been no talk of that to the students.

I’ve had a handful of conversations with those who are much more knowledgeable than myself and the message I’ve gotten is to expect “molten glass” on any/all exposed parts. If you’re OBOGS off and in a controlled ejection situation, get your mask back on, visor down, collar popped, sleeves cinched then let er’ rip.

Haven't heard any discussion about it as a T-6 & T-45 stud nor in the F-35.

I flew the t-45C about 15 years ago... I don’t recall that discussion.

Currently flying the F-35A... and no- no discussion on a manual TRS pull prior to controlled ejection.  I don’t know that it would change anything.

In both aircraft, they have canopy breakers on the seat as well... just like the other 4th gen “normal” jets I’ve flown.

Is the canopy breaker shorter than many pilot’s helmets?

The T-6 can’t jettison it’s canopy; It wouldn’t even come open if you unlocked it in flight. Maybe we should teach ELPs...

Now, if it did jettison, why wouldn’t the ejection sequencer just do that instead of blowing it up in the pilot’s face?

Man, if we bought a screw driver, we’d end up paying $300 for a drill with no bits. smh

When I retire, I’m starting a business for the sole purpose of selling overpriced shit to the government.

I’m quite sure everyone is told at some stage to lower the seat to the point it’s above your head...whether they listen or not is a different answer.

Some of us are not short, so lowering the seat more was never an option.
