## . Siegmund said he didn't see any flapping of wings but he was sure it was a huge fowl and not a type of aircraft. He was riding with a companion, Col. Ralph Jackson, Head of Western Military Academy, at the time. Jackson, however, was talking to a farmer and didn't see it. Siegmund said he didn't mention it to him as it seemed too incredible. Note: A child, James Trares, age 12, said he saw the bird flying over his home in suburban Glendale, Mo., some 3 months previous. The Belvidere report quoted a Robert Price and Veryl Babb as saying the bird was "bigger than an airplane" and flapped its wings. RELIABILITY: Impossible to evaluate. Col Siegmund was never questioned but some sort of investigation obviously should be made in lieu of the fact that he was once commandant of the Air Base at Kearns.
