Is that a record?
Perhaps someone will be clever enough to find out, but I am just grateful as ever to Danny for resuscitating the thread.
Thread drift I know, but quite interesting to note from the thought-provoking link
http://www.fleetairarmoa.org/Content...AA_amp_BoB.PDF that five of the fifty-six FAA pilots who fought in the Battle of Britain were Petty Officers, the equivalent rank/rating to Sergeant. I regret that I do not know when Chief or Petty Officer pilots were phased out of the FAA, although I would hazard a guess that it was probably in the mid 1950s.
