Apparently the "Special Committee on Non-terrestrial Science and Technology" had been working some time in order to define a clear action. Dr. Bush had presumably presented a proposal from the Committee for an aggressive separate program to apply "non-terrestrial know how" to the war effort, but FDR thought that it would threaten the atomic bomb program. Thus, he carefully avoids saying "no," but says that we will "take every advantage of such wonders that have come to us" after we have won the war. Very gracious letter. The classification "double top secret" was a legitimate one. We are currently (May 2000) requesting copies of similar correspondence from the Roosevelt Library for format and typography comparison. The signature, although not a strong discriminate, is consistent with other authentic signatures.
