Martin XB-51
Martin XB-51 (S/N 46-686) with drag chute. Note that the XB-51s are easily distinguished: the first aircraft had a large test pitot tube probe on the lower forward fuselage, and the second aircraft did not. Also the forward fuselage XB-51 logo is centered vertically on the first aircraft and much lower on the second. (U.S. Air Force photo)
