Lets go way,way back to ask,

No.1 "When was an airplane the very-first time employed as a military weapon?" Give Date (month and year?).

And No.2 "In which War?"

1. December 1911

2. Italo-Turkish War

Italian Lieutenant Gavotto chucked some bombs out of his aeroplane onto a Turkish held oasis, Ain Zara in Libya.
