Wikipedia[/url]]As Dickson had predicted, initially air combat was extremely rare, and definitely subordinate to reconnaissance. There are even stories of the crew of rival reconnaissance aircraft exchanging nothing more belligerent than smiles and waves.[10] This soon progressed to throwing grenades, and other objects – even grappling hooks.[12] The first aircraft brought down by another was an Austrian reconnaissance aircraft rammed on 8 September 1914 by Russian pilot Pyotr Nesterov in Galicia in the Eastern Front. Both planes crashed as the result of the attack killing all occupants. Eventually pilots began firing handheld firearms at enemy aircraft,[10] however pistols were too inaccurate and the single shot rifles too unlikely to score a hit.
