He gave me a few details on how a cambered or slotted-vane rotating disk might operate, then interrupted himself to ask me what I thought the saucers were. “They’re either interplanetary or some secret development,” I said. ‘What do you think?” “The N.A.C.A. has no proof they even exist,” he answered. When I left the building a few minutes later, I was still weighing that statement. If the Air Force or the Navy had a secret disk device, the N.A.C.A. would almost certainly know about it. The chances were that any disk-shaped missile or new type of circular aircraft would first have been tested in the N.A.C.A. wind tunnels at Langley Field. If the saucers were interplanetary, the N.A.C.A.—at least top officials—would probably have been in on any discussion of the disks’ performance. Either way, the N.A.C.A.’s official attitude could be expected to match the Pentagon’s. After lunch, I took a taxi to the office of the private engineer. Like D———, he has asked that he not be quoted by name. The name I am using, Paul Redell, will serve that purpose. Redell is a well-known aeronautical engineer. He has worked with major aircraft companies and served as a special consultant to government agencies and the industries. He is also a competent pilot. Although I had known him several years, he refused at first to talk about the saucers. Then I realized he thought I meant to quote him. I showed him some of the material I had roughed out, in which names were omitted or changed as requested. “All right,” Redell said finally. “What do you want to know?” “Anything you can tell us. But first, your ideas on these sketches.” I showed him D———’s drawings and then gave him the high points of the investigation. When I mentioned the mystery-light incident at Fairfield Suisan Air Force Base, Redell sat up quickly. “The Gorman case again!” “We heard about some other ‘light’ cases,” I said. “One was at Las Vegas.” “I know about that one. That is, it you mean the green light—wait a minute!” Redell frowned into space for a few seconds, “You say that Fairfield Suisan sighting was on December third? Then the Las Vegas sighting was only a few days later. It was the first week of the month, I’m positive.” “Those light reports have got me stumped,” I said. “A light just can’t fly around by itself. And those two-foot disks—” “You haven’t worked on the Gorman case?” asked Redell. I told him I hadn’t thought it was coming up on my schedule. “Leave these sketches here,” he said. “Look into that Gorman sighting. Then check on our plans for space exploration. I’ll give you some sources. When you get through, come on back and we’ll talk it over.”
