TLS signed “Robert A. Rushworth,” one page, 8 x 10.25, Air Force Flight Test Center letterhead, August 15, 1962. Letter to a flying enthusiast. In part: “I am sorry that I do not have any kind of schematic drawing of the so-called ‘roller coaster flight.’ Actually the flight was only another research test and newspapermen, looking for an angle, invented the roller coaster phrase...I am afraid it is not possible to send you any X-15 material which ‘no one else would have.’ No member of the Air Force can give anything to the public which is not available to everyone...We know very well that our work could not continue without people like you supporting us. Just by way of contrast to the X-15 I am sending along also a picture of Peter Bowers, aviation historian, in his 1911 Curtiss pusher.” In fine condition. Accompanied by the photo mentioned in the letter, as well as a photo of Rushworth receiving a medal. Pre-certified Steve Zarelli and RR Auction COA.
