ufo flying inside a chem trail.My girlfriend and I were at the park down the st with our 3 children. I Was looking up at the sky at the chem trail left by a plane when I saw What looked like an air plane with no wings. It was moving at a speed faster Than a normal aircraft. I then realized it was not an aircraft but a UFO. I Had never witnessed a UFO before so I went to photograph the craft and when I looked up it was gone. Vanished into thin air. I am convinced that what I Saw was a UFO.((NUFORC Note: Source of report indicates that the date of the event is approximate. PD))
