Full Description & Details

The sighting by my younger sister and I occurred when I was nearly eleven years old in the summer of 1966. My attention was drawn to a metallic reflection near the Wadena Municipal Airport. Thinking that a military aircraft was in the area, I pointed it out to my sister. We then both watched as the object slowly came toward us across meadows and open farm fields. Shortly, it became apparent that we were looking at a lens-shaped silver disc. The object moved from east to west just north of us, very close and at low altitude, affording an unmistakable view of its shape. It was a simple metallic, lens-like object, having no windows or attached structures, and it was perfectly silent. My sister, gloria and I then watched it until it was out of sight. I seem to remember that it abruptly took off, but it was so long ago that I'm unsure of that detail. I had called out to my mother, who was taking a bath before work that late afternoon, but her glasses kept fogging up as she tried to look out the bathroom window, so she unfortunately didn't see the object. I've been deeply interested in UFOs ever since, and I have seen other strange things in the skies, sometimes with other people. I watch the skies constantly, now for about 40 years.

Other Comments

I was favorably impressed when I read your book, "UFOLOGY". Having industrial R&D experience with various gas plasmas, it occurred to me that UFOs were generating a high-powered, microwave radiation-induced plasma about them. Years later, I found your book and discovered that you had very similar ideas. I suspect that the plasmas around landing or landed UFOs may be causing bias sputtering of silicon nitrides from rock silicon and atmospheric nitrogen. Otherwise, sputtering of material from the UFO may be happening. I believe that it's possible that Secondary Ion Mass Spectrometry (SIMS) could be used to detect such chemical traces. It would be remarkable if nitrides were detected, as these do not occur naturally. Likewise, exotic metals would be remarkable. Exposed rocks within the landing ring could be analyzed.
