A Vought SU-1, BuNo 8931, assigned to the Naval Aircraft Factory (N.A.F.) in Philadelphia, Penn., was visiting the Massachusetts Air Guard at Logan Airport, Boston. The aircraft flipped over upon landing and the photo shows damage to the propeller, cowling, left wing strut and the top of the rudder. This mishap took place circa 1936.
