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.

If the shot was fired at a 747 windshield from the ground, the impact angle
would have as much to do with lack of penetration as the thickness of the
material. Also, if a rifle round from a SWAT team, it would just as likely be a
5.56mm (.223 cal) from an AR-15 or similar.
