A bit off the topic but re the BA Museum (see Woodpecker, above).
I was there a few weeks ago doing some "serious" research. They are a devoted, knowledgable and cheerful bunch of unpaid volunteers. If I understand right (and don't quote them on this) they get very little support directly from BA. They have an amazing collection of memorabilia (including a Concorde nose cone).
What is more they hold the BA Archives. Hundreds of files of documents going back to Imperial Airways and beyond. On a par with the National Archives in Kew. I was able to find some original photos of the opening of Sharjah Airport in 1932 and its first flight in by HP42. And all the data on the loss of HP42 Hannibal on its way to Sharjah from Karachi in 1940. And they will feed you with coffee and biscuits while you work.
They are great people and could desperately do with more support from the top brass. And bigger premises to expand into.
