That afternoon the Air Force revealed it was working on a case involving a Navy rocket expert named C. T. Zohm. While on a secret Navy mission to New Mexico, in connection with rocket tests, Zohm had seen a bright silvery disk flying above the desert. He was crossing the desert with three other scientists when he saw the strange object flashing northward at an altitude of about ten thousand feet. “I’m sure it was not a meteor,” said Zohm. “It could have been a guided missile, but I never heard of anything like it.” By this time, saucer reports had come in from almost forty states. Alarm was increasing, and there were demands that radar be used to track the disks. The Air Force replied that there was not enough radar equipment to blanket the nation, but that its pilots were on the lookout for the saucers. One report mentioned a curious report from Twin Falls, Idaho. The disk sighted there was said to have flown so low that the treetops whirled as if in a violent storm. Someone had phoned Purdy about a disk tracked by weather-balloon observers at Richmond, Virginia. There was another note on a sighting at Hickam Field, Honolulu, and two reports of unidentified objects seen near Anchorage, Alaska. A typed list of world-wide sightings had been made up by the staff at _True_. It contained many cases that were new to me, reports from Paraguay, Belgium, Turkey, Holland, Germany, and the Scandinavian countries. At the bottom of this memo Purdy had written: “Keep checking on rumor that the Soviet has a Project Saucer, too. Could be planted.” From the mass of reports, John DuBarry, the aviation editor of _True_, had methodically worked out an average picture of the disks: “The general report is that they are round or oval (this could be an elliptical object seen end-on), metallic looking, very bright—either shining white or silvery colored. They can move at extremely high speed, hover, accelerate rapidly, and outmaneuver ordinary aircraft. “The lights are usually seen singly—very few formations reported. They seem to have the same speed, acceleration, and ability to maneuver. In several cases, they have been able to evade Air Force planes in night encounters.” Going over the cases, I realized that Purdy and his staff had dug up at least fifty reports that had not appeared in the papers. (A few of these proved incorrect, but a check with the Air Force case reports released on December 30, 1949, showed that _True’s_ files contained all the important items.) These cases included sightings at eleven Air Force bases and fourteen American airports, reports from ships at sea, and a score of encounters by airline and private pilots. Witnesses included Army, Navy, Marine Corps, and Air Force officers; state and city police; F.B.I. agents; weather observers, shipmasters, astronomers, and thousands of good solid American citizens. I learned later that many witnesses had been investigated by the F.B.I. to weed out crackpot reports.
