Rick,
I have always wondered that myself. They must have been a real gutsy load of chaps, ready to try anything new.
I have got in my posession an officers swagger stick, with the Royal Flying Corps emblem in silver on the knob (pre April 1st 1918). I have always wondered what happened to the bloke who owned it.
I offered to donate it to the RAF museum at RAF Cosford, but they declined to take it because it wasn't associated with the RAF. No pleasing some folks.
John
