Read an article where a instructor banged out of a TA-4 Skyhawk in the states, late 60's, when the NZ boys were doing conversion.
had a bird strike which entered through the rear half of the canopy hitting instructor in face, knocking out comms and temp full blindness (perm lost 1 eye from memory). Not fully aware of the situation up front, the instructor assumed the worst and away he went.... leaving the surprised and now solo student up front to bring it home. Rescue found the ejectee in a field, all set up in his liferaft.
