Reading flashing light was a piece of cake for radiomen; we went to signal school (at Noroton Heights, Conn.) after completing radio school, so the Morse code had already been drilled into us. We liked best the yardarm blinker because it was operated by key. The hardest part for us was semaphore; it always seemed to be backward. It was helpful, though. I once stood on the fantail of the tanker I was on and helped refuel a destroyer that was escorting us.
