Berlin Airlift: The Effort and the Aircraft by R.E.G. Davies and John Provan (1998)
No one provided more authoritative information about aviation in print than the late Ron Davies, long-time curator of commercial aviation at the National Air and Space Museum. Written with John Provan, author of many books about aviation in Germany, it's a superlative reference to what still stands as the greatest humanitarian airlift in history.
