I remember a fast jet one in the RAF that came through the screen and survived, it was needless to say pissed off and was letting the pilot know, he had to stab it with his knife.

That guy is seriously lucky he never ended up blinded or worse.

Ever remember this one an air to air with another aircraft, sadly one went in, but the Baron pilot landed this
