Richard Todd, (7 (LI) Para): John Conteh (10 Para): Lewis Collins (10 Para) only 'celebs' who come to mind as having para wings.
Parachuting was Lewis Collins downfall. His contract for 'The Professionals' had a no dangerous pastimes clause and he cracked a bone the day before filming a new series started. Apparently he faked tripping over a generator cable to cover it up and the electrician was initially sacked, prompting Mr Collins to do the honorable thing and make a full confession. The production could not continued and his fine just about bankrupted him as well as ending his acting career. Moved to LA and started a software company in the end.
Richard Todd has to top that list though! Imagine being at Pegasus Bridge on D Day, only to go back 20ish years later and do it again in a film. Allegedly wearing the same beret! He was offered the chance to play himself but opted for the Howard role.
