“O.K. Try to get the details of Mantell’s radio report to Godman Tower. Before he was killed, he described the thing he was chasing—we know that much. Project ‘Saucer’ gave out a hint, but they’ve never released the transcript. Here’s another lead. See if you can find anything about a secret picture, taken at Harmon Field, Newfoundland—it was around July 1947. I’ll send you other ideas as I get them.” Before I left, Purdy wished me hick and told me that he would work in closest harmony with me. “But watch out for fake tips,” he said. “You’ll probably run into some people at the Pentagon who’ll talk to you ‘off the record.’ That handcuffs a writer. Look out they don’t lead you into a blind alley. Even the Air Force statements and the Project ‘Saucer’ report contradict each other.” For six months, I worked with other investigators to solve the mystery of the disks. We checked a hundred sighting reports, frequently crossing the trail of Project “Saucer” teams and F.B.I. agents. Old records gave fantastic leads. So did Air Force plans for exploring space. Rocket experts, astronomers, Air Force officials and pilot gave us clues pointing to a startling solution. Many intelligent persons—including scientists—believe that the saucers contain spies from another planet. When this first phase was ended, we were faced with a hard decision. We had uncovered important facts, We knew the saucers were real. If it was handled carefully, we believed the story would be in line with a secret Air Force policy. It was finally decided to publish certain alternate conclusions. The Air Force was informed of _True’s_ intentions; no attempt was made to block publication. In the January 1950 issue of _True_, I reported that we had reached the following conclusions: 1 The earth has been observed periodically by visitors from another planet. 2. This observation has increased markedly in the past two years. “The only other possible explanation,” I wrote, “is that, the saucers are extremely high-speed, long-range devices developed here on earth. Such an advance (which the Air Force has denied) would require an almost incredible leap in technical progress even for American scientists and designers.” Nation-wide press and radio comment followed the appearance of the article. This publicity was obviously greater than the Air Force had expected. Within twenty-four hours the Pentagon was deluged with telegrams, letters, and long-distance calls. Apparently fearing a panic, the Air Force hastily stated that flying-saucer reports—even those made by its own pilots and high-ranking officers—were mistakes or were caused by hysteria.[3] [3] Air Force press release 629-49, December 27, 1949. But three days later, when it was plain that many Americans calmly accepted _True’s_ disclosures, the Air Force released a secret project “Saucer” file containing this significant statement:
