There was a hi-jack in the 80s (?) where one of the military personnel
on the ground attempted to shoot a hi-jacker through the windshield on
a 747 (?) . Nothing happened of course, due to the thickness of the
material. My assumption had been that the round was most likely
7.62mm.

It might have been the hi-jack where hi-jackers threw one of the
wounded crew members onto the concrete apron and he broke his neck as
he hit the ground - but I could be mixing up two hi-jacks.

I have the impression the hi-jack to which I am referring was
somewhere like Teheran or Damascus.
