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]].
This sighting has remained technically an unknown chiefly because the descriptions fail to give the necessary information. What direction did the object come from? How long was it in sight? What balloons had been released in the area that day? At what time? What were the winds at high altitudes? The winds at low levels were from the west, and at altitudes from 20,000 to 50,000 feet they were from the east; but what were they in the region above 70,000 feet, the probable location of the object? Even without these facts, a reasonable explanation can be offered: the unknown was a radiosonde balloon that burst at a high altitude.
The sun was low on the western horizon. A balloon at a great height reflects the sun brilliantly from its rubber or plastic skin and gleams like a giant metallic sphere. These balloons usually soar to 70,000 to 90,000 feet before they burst from the cold. The fragments then disperse in an impressively uniform pattern, and may disappear quickly. The radiosonde package and attached parachute fall rapidly at such heights. They are not noticed by the witnesses because the chute usually does not open fully until after the package has fallen some distance into the beginning twilight near the earth’s surface.
This explanation of the “stack of coins” cannot be proved, of course, but every detail of the incident is consistent with the behavior of a bursting balloon[III-2].
