Quelque chose dans les airs

Time magazine, 11 août 1952, p. 58

Au large des Îles Aléoutiennes, à l'été dangereux de 1943, le détachement spécial de surveillance radar de la Marine repéra les blips de vaisseaux de guerre enemis. In a brisk, 45-minute fire fight, the battle fleet expended more than 1,000 rounds of 14-in. and 8-in. ammunition. From their battle stations, lookouts reported the flares and star shells of the otherwise invisible Japanese. Radar operators called in corrections for what seemed to be near misses. But there was no return fire. Eventually, a bewildered Navy decided that it had been slugging it out with phantoms.

Last week in Washington, Vice Admiral Robert C. Giffen (ret.), who had commanded U.S. forces during the great Alaskan "Battle of the Blips." had reason to recall his embarrassing adventure. Washington itself had just lived through a phantom invasion when unidentified blips on a Civil Aeronautics Authority radar brought jet fighters screaming over from Delaware to hunt "flying saucers" (TIME, Aug. 4). The fighters had shot down no night-flying saucers, but two of them had found radar targets. It appeared later that they had been drawing a bead on each other.

The Navy, said Admiral Giffen, was convinced by now that its Alaskan battle force had steamed in under a high-riding layer of warm air that acted as a kind of electronic ceiling. Radar pulses bounced off the "inversion" layer and echoed back from the Amchitka mountains, more than 100 miles away. A similar temperature inversion was hovering over the capital when the saucers flew in. Admiral Giffen thought that atmospheric conditions were still the best explanation for the ghostly targets.

Crockery. But Washington was not the only city attacked last month by the airborne crockery. From all over the country frightened phone calls and irate demands for information rang through the Pentagon. Air Force intelligence, official guard ian of saucer information, was smothered by an alltime record of reported sightings. Items:

Satisfaction. Last week, in an effort to clear the air and take the heat off its frantic Intelligence Section, the Air Force answered some questions. Major General Roger M. Ramey, Director of Operations, and Major General John A. Samford, Director of Intelligence, did their best to explain away the excitement. All the reports together, said General Ramey, do not establish any pattern that can be construed as menacing. After six years of study, he is "reasonably well" convinced that there is no such thing as a "flying saucer."

Like the Navy, the Air Force was sure that temperature inversions over the nation's capital had permitted high-angling radars to pick up trucks and other moving targets on the ground. But what about the other 1,000 or more sightings elsewhere? In a Pentagon press conference, just as if he meant to be reassuring, General Samford went on to state that such things as missiles, ice formations, birds, meteors, and honest misinterpretations of natural phenomena account for all but 20% of them. That still left plenty unexplained. So the Air Force plans to distribute 200 special cameras to competent observers and has ordered some powerful new telescopes that will scan the sky continuously from horizon to horizon.
