Fatal aviation accident: Beck P-51A near Oshkosh (2007-07-27)
Probable cause: The P-51A pilot's inadequate visual lookout and his failure to maintain clearance from the P-51D. Contributing factors to the accident included the restricted forward visibility of the P-51A, the air race team representative's inadequate flight brief, the failure of the air boss to recognize the lack of separation between the airplanes on short final, and the diminished air/ground radio communications during the air show.
