Early on the morning of May 16, 1946, a U.S. Army B-17 Flying Fortress aircraft crashed into White's Hill (also known locally as "White Hill") near Fairfax, California. Two men were killed and six seriously injured. There were reports that the B-17 was carrying nuclear weapons materials for the Operation Crossroads tests at Bikini atoll, but these reports were not confirmed. However, due to the behavior and activities of the military authorities at the crash site and the reports of several credible witnesses, including several of the crewmembers, questions about the plane's cargo remain.
