Really necessary?
I know Siam and I am qualified military aircrew although not RAF. (Thank god!)
I'm a bit disappointed he has had such rough criticism.
I think that him trading on his award of RAF wings is entirely fair. He did achieve the temporary award albeit without reaching limited combat ready status. He has something to be proud of and if entering the aviation industry why not market his award?!
In the time I knew him, personally and at a very difficult time on a difficult course Siam was never dishonest and he is just trying to get on in life at a difficult time. You trade with what you've got.
Best of luck Siam.
