Ahh yes, the son of the 'father of the jet engine'. Apart from his trademark hat obsession and long-sleeve pedantic Britishness he had quite a sense of humour. Apparently he didn't see the funny side of this one:
F/O in a classic 747 at top of descent reduces the thrust levers to idle at that beautiful smooth rate that doesn't scare the passengers or punish the bleed valves.
Captain W., patronisingly: 'Very good, my father would have been proud of you!'
Aussie F/O: 'Oh, he worked for HAECO did he?'
