There is a anecdote on the Flypast forum that sums the man up admirably and I'm sure they won't mind me copying it over..
A man who lived a truly awe inspiring life, who recalled events as though they had happened only the week before, whether it was in front of an open mouthed audience or afterwards, whilst packing away his slides and artefacts, with such wit and humour.
Ken gave a talk in the control tower at the ex RAF Wickenby just a few years ago, and the crowd was utterly transfixed throughout the whole evening.
The unforgettable 'Ken' moment was when a young lady in the cafe/tower, obviously worried that at 11.00pm after a long day and many many questions, Ken still had to drive through deepest Lincolnshire and Norfolk to get home (several hours drive on unlit roads), thought it would be too much for him or his old Peugeot 205 and asked if he wanted to stay somewhere locally.
Ken; don't worry about me my dear, i'm a night bomber pilot.........................priceless.
RIP Ken
We have just lost a true great - a one off. RIP Ken Wallis.
