what happens with P51D canopy as pilot bails out?
 
Hi all,

that question about the P51D:

as the pilot bails out, do the canopy stay attached on the plane (in the crash) or does it be dettached or "ejected" (automatically? or with pilots help?) from the plane and ...with lot of luck found some years later at some distance of the plane crash-site?

Thanks for any help,

Mathias

The canopy had to be jettisoned by pilot

I don't know if this link will copy, but the bailout procedure is here. Step 1 is slow the plane, step 2 is jettison the canopy. etc...

Does the same hold true for Malcolm Hood equipped B's/C's?

Yes, the hood could be jettisoned. Search for "jettison" on the page below.

Hi,

according with the bailout procedure described in the pilots manual above in same thread (link), could it be possible to give an estimation of the delay between the decision of bailout and the jump out of the plane?
Pilot had to:

- lower seat and head and then
- eject canopy
- disconect headset and oxygene
- open seat security belt and shoulders harness, throught it away on the sides
- get with feets on the seat and then
- jump...

can that all take about 5 seconds? or 10 ? 15?

No idea at all...
Thanks for any possible idea...

You may find the answer on any film of the P-51 bale out at Duxford yesterday, 10 July 2011.

incredible true experience yesterday!

thanks for the information and links;

at the exact moment the pilot was bailing out at Duxford I was trying to find some plexiglas little parts of a P51D canopy in the forest some hundred meters before the Mustang crash site I'm working about;

Do you believe the canopy plexiglas would "explode" in hundreds of little parts as hitting big trees and the ground, or does it "normaly" stay in one or some big fragments - some of them still attached on the metal frame?

No idea at all about the resistance of such a plexiglas part as falling from about 50 or 20 meters high at about 150 mph!

Second hypothese would let few chances of finding something today, first one would be hopefull for a more successfull "fragments hunt"!

thanks for your kind help!

Here's a better view of what happens to a P-51 coup-top.

This does not give the timing, but if you listen he followed the procedure except for the shoulder straps, (which were warned about in the written bailout procedure.) He bailed because his coolant line was cut by a rifle bullet, so he must have been low.

Regarding the Duxford cash, note that after the pilot bails, he still has to fall a bit before the chute can open. In the crash you are investigating, it would seem the pilot was way too low for the chute to deploy, even if he could have gotten out.

great documents! very interesting for me!

I now have to look on the ground in the forest along an about 100m bright and 1000 meters long band with the hope of being a little lucky!

But its stays possible that the canopy was jetissoned 5 minutes earlyer...

A good place for seraching mushrooms surely this summer!

Maybe something will be found...little plexiglas parts would be enough!

thanks for your very kind help!
