Went out my back door to have a last smoke sometime around 9:30PM. Clear night. I happen to look to the east and when I did a cylinder shaped object darted between tree branches three houses away and next door neighbors roof. It was bright like looking at a led flood light. From the center of it to a plume at the tail, the light had a pale blue hue like a gas flame outside the bright light. When I saw, I was like what was that and ran to the front of my house. Nothing, it was gone. But it stayed with me on my mind, even though I passed it off as a shooting star or something along that line. Almost a month later, same thing happened in the exact same location as the first time. The path it took heads to Long Island Sound. There is an airport on that path, Tweed New Haven and I have seen uncounted flights heading to Tweed through the years. This was no jet. To low, wrong shape, the bright white light with blue glow and plume, and most of all the speed. Both times if I had blinked, I would not have seen it. My date is not totally accurate but as close as I can get. Saw an article this year online about object seen in space by either a telescope or explorer rocket. It a lot like what I saw. Once pass it off twice in same place mind blowing.
