Having always been fascinated by the Berlin Airlift and a frequent visitor to Berlin over many years I have read most of the accounts of the Airlift in print.
This is by far and away the best one I have read - not perfect but very, very good indeed. Although written by an American it the first account I have read that give due credence to Britain's contribution to the enterprise which was a pleasant change.
It is an interesting mixture of plain history, personal accounts and discussion, which despite the mix has the sense to retain a chronological narrative unlike the ramblings of, for instance, the Sutherland and Canwell acount, or the Andrei Cherny one.
Hers is also the first account that properly emphasizes that tonnage wasn't everything - we have this lovely view of planes flying in sacks of food for the starving city, whereas in fact almost 70% of all the loads by weight, especially the US ones in the bigger C-54s, was coal!
