[Richard T. Eger]

Dear Ed,

Like you, I've wondered why we haven't seen a good book that covers the postwar employments of the Paperclip individuals.

The Wikipedia article on Lippisch doesn't say whether he was involved or not in the early post war delta aircraft work done in the U.S. by Convair. It picks up his history in 1950 when he worked until 1964 for the Collins Radio Company in Cedar Rapids, Iowa, which had an aeronautical division. By this point, his interests lay elsewhere than continuing his delta wing research. His collected papers are archived at Iowa State University, so I don't think his work at Collins was a subterfuge for "secret" delta aircraft design work. Whether or not he consulted with Convair on their F-102, F-106 and B-58 designs isn't stated. I don't see any reason for subterfuge on the subject of his involvement or lack thereof at the point of time of these developments.

Prof. Messserschmitt and Lippisch did not get along and Lippisch left Messerschmitt in 1943 for other employment. It is thus possible that Lippisch had a difficult personality and this may have kept him out of employment with the major U.S. aircraft manufacturers, but then I'm only guessing.

Regards,
Richard
