Thre Royal Canadian Air Force provided Britain with highly skilled radar technicians — “the Secret 5,000” An unknown percentage of this group flew on patrols over the Atlantic Ocean to detect German submarines and aircraft. These radar technicians were not eligible for the Air Medal because they were listed as ground crew, not air crew. The RCAF classified all information on this topic - to be released in 2045. I know RCAF No. 407 Coastal Strike Squadron (Coastal Command) was involved. Does anyone know of other links or information?
