Less than one month to a prior sighting of a pitch black light absorbing square, I witnessed it again on the opposite side of the sky. This time while moving it started to leave 4 straight lined vibrant blue lines then completely vanished out of site. It traveled roughly four inches across the sky, while leaving 4 lines one from each edge of a vibrant blue color. There was no arcing to the trails and they vanished immediately with the vehicle. Having always wondered what I was seeing, after viewing an episode of Hangar 1 with Bob Lazar and further research into the subject. It would appear that according to his explanation it turned on its warping technology, then engines, turned said engines off then disappeared through it’s warp. Definitely an amazing site to see, the psychological aspect, was that I for some reason though of the word sita(Spanish for star and further a nickname for a friend I knew, but had not thought of for years.) before I decided to head out for a cigarette.
