Silent red light flies and disappears over neighborhoodWitnessed a red, round light climbing upward from the horizon on Oct. 6th, 2012 at about 9:30PM. It appeared to flicker and although it was flying straight, it had a strange almost twitchy movement to it. I was ready for it to be a helicopter, but it made absolutely no sound as it passed over us. It crossed over slowly, the light dimming, until it disappeared completely, right in the middle of the sky. The area it went through had other usual plane traffic, all which were audible and seemingly at the same height.
