The objects looked and behaved like balloons. Another possibility is that they were fragments from the balloons that had burst earlier. But the explanation of this incident remains unknown because too few facts were determined. _Plastic UFOs and the “Stack of Coins”_ A burst balloon has caused many a saucer scare, but the invasion of Farmington, New Mexico, on Saint Patrick’s Day 1950 was one of the most dramatic. The “saucers” began to fly about 10:15 A.M. M.S.T., and soon filled the air. In numbers estimated from 500 to thousands, for the next hour the gleaming saucer-shaped objects soared over the town, moving erratically at incredible speeds, darting in and out among each other in what one writer has called “the greatest exhibition of magnetic flight that has ever happened in this universe.”[III-6] (See _Chapter_ IX.) The explanation is more prosaic. A Skyhook balloon had been launched that morning from Holloman Air Force Base near White Sands, New Mexico. Near Farmington, in the cold atmosphere at 60,000 feet the balloon had become brittle, burst, and disintegrated into hundreds of tiny pieces of plastic. Light as feathers, shining in the sunlight, they floated over the town and away[III-1, p. 106]. A similar episode occurred on July 27, 1952, the day after the second Washington “invasion.” The dramatically named “stack of coins” sighting at Manhattan Beach, California, was reported by an aircraft engineer, formerly a Navy pilot, and was confirmed by seven other witnesses. At 6:35 P.M. P.S.T., just before sunset, a bright silvery object appeared high in the sky, elliptical in shape and apparently solid. The size was estimated to be about that of a dime held at arm’s length. As the observers watched, it turned to the south and gracefully broke apart into seven smaller objects, as smoothly as a stack of coins separating. The three lead objects assumed a V position, the others followed in two pairs, and the whole formation then turned northeast and quickly disappeared. ATIC investigators, still buried in a mass of equally spectacular reports, could provide no solution to the mystery, and another fleet of saucers had apparently been added to the summer’s list. Immediately concluding that the objects were from outer space, UFO-philes pondered the meaning of the incident. One author suggested that the disks might have been seven different ships that, when first observed, had been stacked like coins and attached to each other by some magnetic force, so that all could be directed as one[III-5].
