That RAF bloke reminds me of the tubby types who used to come into my militaria shop and start looking at badges and ask if I had an SAS beret badge as they had lost theirs. Or the others with similarly impressive waistlines who told me they had been in the services, but with much winking and nose tapping told me they weren't allowed to speak about it!
Interesting error in the article which implies that only officers can be awarded the DFC as "only officers are pilots in the RAF". NCO aircrew can be awarded the DFC - does anyone have an example?
