A California college physics teacher watched a triangle-shaped UFO that came within several hundred feet and then silently moved away at 9 p.m. on April 15, 2010, in Ventura, according to testimony from the Mutual UFO Network (MUFON) database.
The instructor first heard a screech sound, then watched the object move quickly across the sky.
"At first it looked like it was a large bird high in the air as the front and two sides were heavily darkened against the mostly dark sky," the witness stated. "It was moving toward me and over a period of about 2 seconds it became clearer and resembled a hang-glider. It was descending and moving toward the east and seemed to be gliding smoothly, making no sound that I could hear."
The witness then described the object as it reached its closest point.
"It was an equilateral triangle and had three circular areas symmetrically placed near the tips. There was a slight contrast between the gray triangular area and the circular areas, as the circular portions had a very faint glowing quality to them."
The object appeared to be two dimensional during this 8-second sighting.
"As it silently continued moving away from me, the craft seemed to have only 2 dimensions. It looked completely flat like it was a projection. It began to gently ripple with smooth wave patterns and disappeared within a little over a second after doing so. The total event lasted around 8 seconds"
