Blue Fox in SHAR FRS1 was a derivative of Sea Spray in RN Lynx. An oft-asked question was why Sea Spray didn't have a 'Blue' designation. Blue Tit had been mooted, but for some reason not adopted. Some people were quite touchy in those days. In 1986, Director General Aircraft (Navy), an Admiral, jumped on the suggestion that the FRS2 (later FA2) radar trainer be called Sea Harrier Intensive Trainer. The young Lieutenant RN who suggested this was given a career brief on his brief career.
