On Saturday June 21st, shortly before noon, I was in our yard at home when I happened to glance up at a passing plane. I would say this was a two motored one from one of the army bases, flying south at about 10,000 or 12,000. feet. On the mere glance at the plane a bright shiny flash attracted my attention, coming from approximately two or three thousand feet lower than the plane, but slightly ahead of my line of vision of the plane. My first thought was that the plane had thrown out hand bills, but this could not be as they (the flashes or disks) were ahead of the plane. One thing different tho, it seems to me they were not traveling as fast as the plane. We realize to, now, that whatever they were, they must have been quite large, being as plain as the nearest one was, yet so high. And again, they were traveling south against prevailing winds. At least some of the smaller flashes, if not all were as high or higher than the plane, but the nearest one seemed lower, both when it flashed and otherwise, as it did intermittently. RESTRICTED
