Shooting at aircrew who've had to bail out is a war crime............
Quite so BEagle, it is against Article 42 of the Geneva Convention to shoot an airman in a parachute..........
1. Who's going to inform the folks in Syria who killed the aircrew of the Sukhoi downed over Turkey?
2. Was Imperial Japan a signatory of the Geneva Conventions of 1864, 1906, and/or 1929?
3. Did Article 42 even exist prior to the 1949 Conventions?
FWIW, it was not uncommon for aircrew to be shot at in their parachutes during WW2. All sides did it. It was not yet a crime then.
