Another Broads sailor sadly lost. Not a friend although I did know him to talk to, we both belonged to the same sailing club. His mum-in-law lived opposite to us, good friend to my wife, she was so proud of her son-in-law & the family often stayed over whilst dad was away. It wasn't uncommon for Concord to fly overhead but probably with passengers aboard so it was generally a sedate fly pass so to speak, just to say hi to his family I suppose! There is mention of two flights over Oulton Broad in the article but there was a third that I don't think included the sailing club and that was when Concord did what I believe to have been the final flight around Britain. I just happened to be in the garden when she came in low and slow, along our road so to speak before heading upwards over Mum in Law's house, massive power on, memorable!
