William Faulkner has some wonderful stories about the WW1 days when people would go up in these rickety planes with a handgun, and take potshots with it with one hand while they flew the plane with the other, or take up a big basket of hand grenades and be lobbing them down at people on the ground while the people on the ground were shooting at them with infantry weapons.
Pilots in war have always been nuts, but there's levels of nuts.
