TLS signed “D. K. Slayton,” one page, 8 x 10.5, NASA letterhead, September 6, 1977. Letter to a space enthusiast. In part: “We have not written any books except for the early one put out by Life magazine. I do believe that life exists on other planets but do not consider UFO’s as a necessary part of that theory. UFO means only an unidentified flying object which can be explained by many phenomenon unrelated to other planets. I suppose my most exciting moments as an astronaut were during the Apollo/Soyuz flight since it is the only one I have flown.” In fine condition, with a paperclip impression to top edge. Intriguing content, as not many astronauts are willing to share their theories on extraterrestrials. RR Auction COA.
