My father was a USN Crew Chief for a PBY (Patrol Boat Plane, aka sitting duck.) He had orders to leave for Okinawa in Mid August. The bomb probably saved his life. My thanks to Einstein and Fermi!
My dad was a pilot in VP-11, also a PBY. (Although they added four .50 caliber in the noseto be fired with the gunner straddling them!)
