Ml Aviation Ltd -a Secret World by Carter Graham: Keyham Books, Cippenham 9780952771562 Paperback - Baggins Book Bazaar Ltd
More a document of historical record/ interest than a technical study but actually makes for very light reading which is actually enjoyable, especially since it gives a (for this reader anyway) very fresh perspective on the origins and development of the British ejection seat, the accident that claimed the life of Wimpey Wade and a host of other projects and programs that the company engaged in.
Very interesting reading and surprisingly (given the book was published in 2006) that I think you'll find many things are written about for the first time.
