 | Operating in the vicinity of the Coral Sea, April 1942. Photographed from a TBD-1 torpedo plane that has just taken off from her deck. Other TBD and SBD aircraft are also ready to be launched. A F4F-3 "Wildcat" fighter is parked on the outrigger just forward of the island. Other ships in company include a fleet oiler, a destroyer and a heavy cruiser. This view has been retouched to censor the radar antenna mounted atop Yorktown's foremast. Credit: NAVY. |  | Photographed circa 1940, with TBD and SBC aircraft parked on her flight deck, aft.

He was the only survivor of the 4 June 1942 Torpedo Squadron Eight (VT-8) TBD torpedo plane attack on the Japanese carrier force. Gay's book "Sole Survivor" indicates that the date of this photograph is probably 7 June 1942, following an operation to repair his injured left hand and a meeting with Admiral Chester W. Nimitz.
