In fact, the Fifteenth Air Force did drop bombs on it by accident on 13 September 1944, when SS barracks were hit by bombs falling short of their intended industrial targets. The question rather becomes one of the likelihood of hitting the four main gas chamber/crematoria complexes along the west side of Birkenau, and the likelihood that bombs would have fallen in profusion on the rows and rows of adjacent prisoner barracks.
