questions about the canopy of the P-51D and bail-out process

[Flyingkag]

hey all,

I have some questions about the "tear-drop" canopy of the P-51D;

Is it made in plexiglas?

Do you believe that on a crash happening nearly horizontaly in a forest, the canopy would be scattered in some tenths, hundreds or thousands of parts, as hitting the tress/ground with high velocity (about 250km/h probably);

Fact that I have found not one single part of plexiglas or canopy frame on a crashsite, but thousands of other little parts scattered on a 200 meters long trajectory, (including instruments parts coming out from the instruments panel) should I conclude that the pilot had jettiseoned the canopy before the contact with trees and ground? (maybe in hope of bailing-out ashort time before?)

And about bailing-out:

How many seconds should a pilot need for succeeding in an emergency bail-out (when- for example - the pilot discovers he cannot avoid to hit a mountain in front of him, flying in a valley); how long should it need for opening seat-belt, jettison the canopy, disconnect radio/other jacks, put his feets on metal seat, ...and jump out of the plane? Should it need 5 seconds? or more maybe? No idea...

Thanks for any possible help,

Best feelings from France, Mathias
