On March 28, 1975, Goldwater wrote to Shlomo Arnon: "The subject of UFOs has interested me for some long time. About ten or twelve years ago I made an effort to find out what was in the building at Wright-Patterson Air Force Base where the information has been stored that has been collected by the Air Force, and I was understandably denied this request. It is still classified above Top Secret."[97] Goldwater further wrote that there were rumors the evidence would be released, and that he was "just as anxious to see this material as you are, and I hope we will not have to wait much longer."[97]
The April 25, 1988, issue of The New Yorker carried an interview where Goldwater said he repeatedly asked his friend, Gen. Curtis LeMay, if there was any truth to the rumors that UFO evidence was stored in a secret room at Wright-Patterson Air Force Base, and if he (Goldwater) might have access to the room.
According to Goldwater, an angry LeMay gave him "holy hell" and said, "Not only can't you get into it but don't you ever mention it to me again."[98]
In a 1988 interview on Larry King's radio show, Goldwater was asked if he thought the U.S. Government was withholding UFO evidence; he replied "Yes, I do." He added:
I certainly believe in aliens in space. They may not look like us, but I have very strong feelings that they have advanced beyond our mental capabilities... I think some highly secret government UFO investigations are going on that we don't know aboutand probably never will unless the Air Force discloses them
