Also Jonathon Palmer, and all the various HRH's.
There was also a notable Lord, who was trained by my helicopter instructor. After gaining his licence, the Lord used to ask the helicopter instructor to fly the helicopter for him when he was unable/incapable for one reason or another (The butler did his pre-flights!).
One one particular weekend, the Lord asked my instructor to fly his helicopter down to the Channel Islands. My instructor was going to do it, but was thankfully prevented by his wife who had other plans for the weekend.
I say "thankfully" because the Lord had to take the helicopter himself, and awaiting his arrival were the police who promptly arrested him for the drugs which were hidden in the helicopter.
Made my instructor shudder for some time afterwards to think how close he had come, quite innocently, to potentially ending up in the clink, as happened to the Lord!
(I shall refrain from mentioning any names as it saves me having to go back and put "allegedly" in all over the place.)
