Howard Hughes
I had the pleasure of flying with Howard Hughes in 1973 in England in both the Avro 748 and the HS125. He hadn't flown for 13 years but he actually flew very well. He knew exactly where the ground was but the problem was he liked to land on the first few feet of the runway which was very scary and no doubt frightened quite a few people besides myself. He remarked 'You're not the first guy who critcised my landings'. He was a very pleasant and knowledgeable avation man.
With regard to moving the Spruce Goose to Mcminville there is a splendid DVD showing how it was done obtainable from the Museum and it was organised by Jack Real, a true friend of Howard right to the end.
After the flight some test instrumentation was added to the right of the pilot, see page 161 of Tony Blackman, Test Pilot (sorry about the plug!)
