Rig Air-Air Anglia circa 1970. From left Jim Crampton (Joint MD) - RAF Wellington Captain and POW. Dougie Brown- RAF Master Pilot. Brian Sharman - RAF Fighter Pilot post-war. Jerry Fawke RAF Pathfinder (617 Squadron) and Wilbur Wright (Joint MD) RAF Engineer. All sadly departed now. Perhaps fairly typical of civil aircrew composition particularly in smaller firms post-war.
