Description: This was taken above Washington, D.C. on October 29 1942. An object at the very right of the frame was initially thought to represent a high-wing monoplane flying down and right from the upper left-hand corner. Unusually it appears too fast for the shutter, its configuration is more disk-like and it is followed by an exceptionally long dark streak (this extends back and upwards to the top of the frame) that is normally associated with jet aircraft.
