Fareastdriver, Thanks for posting the B36 film. They used to come over South Wales quite a lot when I was at school and I remember that distinctive sound very well. Being so big, they were obviously a lot higher than they looked and they seemed to take ages to pass overhead. We also used to see a lot of the Brabazon which had some similar characteristics, although much smaller. I think that a B36 "landed" at Old Sarum in 1952 after misjudging the approach into Boscombe Down.
