My wife spotted a red/orange light through our Lounge window, we went outside and it was travelling left to right from our back garden looking north. It appeared to be going at a speed you would expect a helicopter to travel at but there was no noise whatsoever. There was no wind to speak of and I would estimate that it was a couple of hundred feet in the air.It moved at a constant speed and disappeared over the houses. I would be interested if anyone else has seen this
