The remarkable Pete Shepherd of the Navy's Historical flight told me this little tale.
Prince Charles was on a visit aboard Ark Royal. Pete, as LSO, was given the job of showing him around but HRH made it clear that he would like to visit the flight deck during land ons. Pete explained as much as he should, but further told HRH that it was a dangerous place to be and particularly pointed to an escape chute that went down a deck or two in the event of a nasty.
"Sir, this chute should be used as an emergency exit for both of us on my say so, that is to say that if an aeroplane, or a wire breaks, that is the way we go. Sir, one other thing, your Mummy has no doubt told you that you are first in line of descent, but I am here to tell you that should there be an emergency you will follow ME in the descent".
With his usual large pint in his hand, and coming from his lips, it was a story as believable as any.
