A friend sent me this recently. It has some very interesting articles and pictures covering the lend lease airforce in WWII.
Articles example:
When the number of airplanes supplied to the USSR is discussed, many publications compare this number with the total production of the aircraft in the Soviet Union. However, it should be noted that the total of almost 5000 Aircobras is comparable to the total production of 4560 Yak-3s, or 5661 Yak-7s (the list could be continued). This number, therefore, is equivalent to a large aircraft factory, one which would have been designed, constructed and supplied with manufacturing equipment and a trained workforce, as well as state-of-the art technologies.
