The Air Corps suffered a great loss and grieved to learn of the death of Colonel Leslie MacDill, as the result of an airplane crash on the morning of 9 November, 1938, in Washington D.C. The accident occurred several minutes after his take off from Bolling Field in a BC-1 aircraft.

Accounts pieced together from numerous eyewitnesses indicated that something went wrong with the motor. Colonel MacDill first tried to get back to Bolling Field, and then with death staring him in the face, aimed his plane for a narrow space between two houses. The descending plane cut down telephone and power wires, knocked down a pole, clipped off tree limbs, plunged to the ground and burst into flames. Colonel MacDill and his passenger Private Joseph G. Gloxner were killed instantly.

Colonel MacDill was one of aviation’s early pioneers, and those who knew him well realized his special ability, his highly analytical mind, as well as his professional attainments. His sound conclusions and helpful advice were constantly relied upon.
