I'm an aviation enthusiast.
As well as being IEng, MRAeS and a practicing engineer in Continuing Airworthiness Management with over 50 years military and civilian experience in electrical and avionics maintenance. My comment about civilians was simply to point out that aviation is as much a civilian business as military, regardless of the end-use of the machine. The Sea Vixen is an aeroplane and the background of its maintenance and operating crews is irrelevant as long as they are aviation professionals.
