This was told to me by Lt Cdr the one only Pete Shepherd, longtime ardent beer drinker and super Sea Fury display pilot.
It seems that a young Prince Charles was invited aboard Ark Royal, then with Sea Vixens and Buccaneers (Pete did a brilliant display in the SV too!), and was invited to join Pete as the duty DLO. He told HRH that some Bucs were due anytime and the landing deck was a place that could be 'nasty.' He then proceeded to explain to the young prince that when an aircraft approached the carrier is was all "guess work" and "chance." At this time they were standing very close to the escape chute and began his lecture to HRH on what happens "if an aircraft gets in trouble or a cable breaks" and then proceeded thus; "Sir, if something nasty does happen you must jump into that chute and get out of the way ASAP." Then followed with "now, your mummy must have told you that you are first in line of descent, but I am here to tell you its wrong, I am first and you follow me."
Great guy was Pete.
