Fast jet-bird strike
I seem to recall there was a bird strike on a Hawk at Brawdy (I think) where the bird went through the forward part of the canopy , struck the pilot's helmet then took out the box on top of the seat which deployed the drogue chute . The front seater was incapacitated & couldn't eject or see to land the aircraft , however the back seater was un-injured & was able to safely land the aircraft .
