Now, if our space-exploration program is just reversed, it will give a reasonable picture of how visitors from space might go about investigating the earth. Such an investigation would tie in with the general pattern of authentic flying-saucer reports: 1. World-wide sightings at long intervals up to the middle of the nineteenth century. 2. Concentration on Europe, as the most advanced section of the globe, until late in the nineteenth century. 3. Frequent surveys of America in the latter part of the nineteenth century, as we began to develop industrially, with cities springing up across the land. 4. Periodic surveys of both America and Europe during the gradual development of aircraft, from the early 1900’s up to World War II. 5. An increase of observation during World War II, after German V-2’s were launched up into the stratosphere. 6. A steadily increasing survey after our atomic-bomb explosions in New Mexico, Japan, Bikini, and Eniwetok. 7. A second spurt of observations following atom-bomb explosions in Soviet Russia. 8. Continuing observations of the earth at regular intervals, with most attention concentrated on the United States, the present leader in atomic weapons. (Saucers have been reported seen over the Soviet Union, but the number is unknown. There is some evidence that Russia has an investigative unit similar to Project “Saucer.”) There are other points of similarity to the program of American space exploration that I have outlined. Most of the extremely large saucers have been at high altitudes, some of them many miles above the earth. At that height, a space ship would be in no danger from our planes and antiaircraft guns and rockets. The smaller disks and the mystery lights have been seen at low altitudes. Occasionally a larger saucer has been seen to approach the earth briefly, as at Lockbourne Air Force Base, at Bethel, Alabama, at Macon and Montgomery, and other places. It has been suggested that this was for the purpose of securing atmospheric samples. It could also be to afford personal observation by the crews. The numerous small disks seen in the first part of the scare, in 1947, fit the pattern for preliminary and close observation by remote-controlled observer units. As the scare increased, the daytime sightings decreased for a while, and mystery lights began to be seen more often. This apparent desire to avoid unfavorable attention could have been caused by our pilots’ repeated attempts to chase the strange flying objects.
