Breguet-Michelin BUM

The Michelin brothers volunteered to build copies of the Breguet BU3 prototype, but they envisioned the plane would serve better as a bomber than a fighter. Fifty were built with the 200hp Canton-Unné engine and designed the Breguet-Michelin BUM (aka the BM10). "BUM" stands for "Pusher, Canton-Unné, Michelin". They served in 1915-1916 with the similar Breguet-Michelin BLM and the Breguet-Michelin 4 in some of the earliest dedicated bombing units.
