## CONFIDENTIAL The object, sighted at ten o'clock off his left wing, appeared to be a silver disc. He immediately completed a sharp bank to the left and was able to get a better look at the object, and described it as follows: "Top part of the object approximately eight feet in diameter, silver in color, had the appearance of a parachute. Attached to the bottom of this had been a dark cable or shroud which appeared to be approximately five feet long. Suspended upon the cable had been a large canister or ball (Colonel Hughes could not discern which) also silver in color. This canister or ball had the appearance of being slightly to the rear of the top part of the object. The overall appearance of the object, looked something similar to the parachute and canister containing photographic testing equipment dropped from a V-2 rocket." At the time he lost sight of the object, "ughes' aircraft had been indicating 310 miles per hour air speed, and the object had appeared to fly away from him on a horizontal plane rather than a vertical decline. A sketch of the object is attached. ## CONFIDENTIAL
