On more than one occassion, and over a span of decades, I have seen completely dark objects, "flying" in straight-line paths at night. Detected only by their silhouettes, as stars and the Milky Way winked-out when they passed. Always very fast, 10-20 degrees per second. At first I thought about bats, owls or some other nocturnal bird, but they usually fly in a formation of 3. Completely soundless, even minutes afterwards- so I don't think they could be supersonic jets. When they were detected, it was usually several times during the same night, sometimes multiple passes over parallel courses. Then no sightings for years and years. I have seen them mostly over the desert, can't recall seeing them over an alpine location. Anybody else ever notice these things? Any ideas besides hallucination? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
