Just a thought??? What if the OP is..... "The gentleman in question claims to have flown Hawks in the RAF in the mid to late 1970s" and looking for info?
Bet you never thought of that. It was quite a common ploy by myself and other operators in MI6 to gain intelligence.
I did as posted in 2007 and disappears for 6 years and then come back digging for info. Probably on level but could also be a journalist.
