The 477th was a medium bomber group, and like most medium bomber groups of their day they flew the B-25 Mitchell. The B-25 is a twin engine medium bomber that was manufactured by North American Aviation. North American Aviation Inc. was founded on December 6, 1928 by Clement Keys as a holding company that bought and sold interests in various airlines and aviation-relation companies. However, the "Air Mail Act" of 1934 forced the breakup of such companies. So in order to continue business North American Aviation started building planes for the war effort. North American Aviation was responsible for a number of historic aircraft like the P-51 Mustang, F-86 Sabre Jet, the Apollo Command and Service Module as well as the B-25. Despite all of this company’s glory, North American Aviation was bought out in December 1996 by Boeing. Although this company no longer exists North American Aviation was responsible for many of our countries greatest aircraft.
