Aircraft Noise Last Night
I am a current airline pilot with 22000 hours and I do not think I am an idle speculator. This morning at 0130 I was awoken by the noise of an aircraft circling the area where I live. At first I thought that it was somebody on one of these small scooters with the two stroke engines that you can hear for minutes after they have passed. It was however an aircraft, it had navigation lights and an anti collision beacon. It circled for 20 minutes about the same point a though it was circling on a fix. As it approached I could just hear the beat of blades but for the rest of the time it sounded like the scooter. I guess it was a helicopter but from the scooter sound it seemed a very small one. I live in SE London near Croydon. Any Ideas
