I met Jock Dalgleish in the mid 70's in the bar of the Royal Scot Hotel on Glasgow Road, Edinburgh - I think it's now a Marriott. I don't know how we got away with it even 45 years ago but we operated a Bolkow 105 out of the hotel car park, flying crew change flights lasting just a few minutes to the Wimpey Sealab near Inchkeith island. The helicopter was left overnight in the car park whilst we kipped at the hotel. We must have been mad! Jock of course saw the helicopter in the car park and he sought us out in the bar. An entertaining character I seem to remember.
King Hussein was mentioned by UP. I once had the privilege of flying him in a JetRanger into Battersea Heliport. What a very pleasant and charming individual! The dual controls had been left in from an earlier training trip and when I tried to usher him into the rear seats he asked if he could sit up front and perhaps have a few minutes flying the helicopter. I probably shouldn't have done it but it's difficult to say no to a King!
