On 4/20/67, four F-4D Phantoms call signs Blondie 1, 2, 3 and 4 were on a Ground Attack Practice flight which consisted of simulated armed reconnaissance with a simulated attack on a stationary target. During the flight, Blondie 3 (#65-0656) made a simulated attack on a truck in an open area north of a mountain peak. Blondie 3 was observed in an approximate 45 degree dive in his attack. While in the drive recovery, the aircraft was seen making two complete rolls to the right and impacting the side of a mountain. Killed in the accident were the pilot 1Lt Donald H. Wolber and aircraft commander 1Lt Douglas B. Rose from the 476th Tactical Fighter Squadron, George AFB.
