but I gotta see this over-the- shoulder shot performed
It's not that hard a shot to do when you are standing on the ground.
In the air a little bit of CAT and whoops, one dead pax, Never mind, plenty more left.
The type of ammo that has been approved is a special expanding shell type, they are designed to puncture the body but not to exit.
The idea is not for airframe protection but for passenger protection as normal bullets will exit the terrorist and hit people behind or go through seats.
Also, How does our gun-totting pilot handle a terrorist holding a grenade with no pin? One shot, he drops the grenade and boom..... Game Over.
