Intelligence summary

This document discusses a UFO sighting involving a pilot and the FAA's investigation into the incident. The pilot reported seeing an object that moved in ways inconsistent with known celestial bodies, leading to a debate over the nature of the sighting. The FAA's analysis of radar data was inconclusive, and the document highlights the complexities of interpreting such phenomena.

AINES COULDN’T H buy the theory. It focused only on the very end of the 50-minute episode, and did not take the crew’s entire experi- ence into account. “There’s no way it could be a planet,” he says. “The autopilot was flying the airplane in a straight line. Terauchi tells me that the object first appeared at 12 o’clock, then moved out rather quickly to 10 o’clock or 10:30 before it came back again.” That’s not Jupiter, he says, because Jupiter doesn’t move. “If the airplane is stable ... and Jupiter is stable, it doesn’t ex- plain this business” of the objects moving back and forth. Besides, he says, the objects were way too big to be planets. When the story about Klass’ Jupiter theory came over the wires at the Anchorage Daily News, Hal Bernton called up Ter- auchi. The pilot was adamant — he had recognized Jupiter during the flight, and whatever had tailed him was no planet. Klass laughed when told that the pilot had rejected his explana- tion: “This is par for the course. When a person is a dedicated UFO believer, as the pilot is and was, he’ll always deny a prosaic explanation. You know, of course, that he’s a UFO repeater.” Klass wag referring to the cap- tain’s second interview with the FAA. When asked if the Nov. 17 sighting was the captain’s “first experience,” the captain told of two other occasions. Once, from his home, he had observed bright lights for 10 minutes at what he judged to be 10,000 feet. And five years ago, on a cargo flight south of Formosa, “when we start climb we saw lefthand side big mother- ship.” But he said it was too “weird,” he wasn’t feeling well, and he ignored it. Asked to comment on these remarks, Steucke said, “The fact that he saw a couple of other gs, I think, is overweighed by the tha alanoe of the fact that he’s a captain for a large airline and has flown for a long time and has a great deal of responsibility.” AT A CERTAIN POINT, THE FAA decided not to release any more information until all the material had been gathered and scrutinized. While the lid was ‘on, Elias, the air-traffic manager, handcarried the radar disc pack to Washington and picked up Harvey Saffer, the FAA’s aiSotbe of Air Traffic Evaluations and Analysis. Their mission was to take a final good look at the radar returns, with the help of the staff at the FAA Technical Center in Atlantic City. The computer there could regenerate the signals into a pattern by stringing them together like pearls. They looked and looked and looked at it. They played the radio tapes, trying to re-create the actual scenario. Five times they looked at it. “We come to the conclusion,” says Elias, “that, uh, you know _ we can’t confirm nor deny. If the [crew] had never said any- thing, we would have said, ‘We see that every day.’” It would have been passed off as a split beacon or “uncorrelated target.” This occurs when the signal coming off the skin of the air- plane aad the signal coming out of the airplane’s transponder don’t hit the ground at exactly the same moment. “It’s just like an echo,” says Elias. On the radar scope, it looks like a little dot next to the slash that represents the airplane. Elias noticed one odd thing: The dots jumped around in relation to the slash. It wasn’t unheard of, but it wasn’t usual either. What may have caused the split beacon was not determined. But both Steucke and Elias agreed that the coincidence was extraordinary — a crew reporting something outside their window and on their cockpit radar, at the same time that both the military and the FAA were receiving inter- mittent radar signals in the plane’s vicinity. Steucke passed off the synchronicity of events as ‘“Sronic.” Says Elias: “You can’t be abso- lutely positive. That’s an honest answer. ... The FAA is not saying it positively, absolutely, without a shadow of a doubt, is a split beacon.... We neither confirm nor deny.” Elias returned to Alaska with his inconclusive results. “The Ad- miral,” FAA administrator Don- ald Engen, an old jet pilot, wanted to be kept abreast of what was what, so Elias and. the con- troller briefed him by phone. And someone on Harvey Saffer’s staff briefed the presidential science adviser. BY THIS TIME, ALL THE MA- terials related to the Nov. 17 sighting were trickling into Paul Steucke’s office from half a dozen different places, and he sched- uled a news conference for March 5 in Anchorage. He also drew up an extraordi- nary order form of re- lated to the sighting = Terauchi’s narrative report, for instance ($1.10), or tapes of = versations between ground con
