Any aviation experts like to help me out with this one?
Couldn't sleep, nipped out of the front of the house for a fag, in the distance I see a blue light in the sky. I watch it and see it morph into a winged object flying across the sky. It's flying from my left towards the city so I figure a plane is coming into Birmingham airport to land and wonder what exotic place the people have just come from.
Then the object changes direction and goes left! And I think, ok, a helicopter. As I watch it fly the lights change from blue to red, but not according to it's direction, just seemingly random. And the lights are all flashing, sometimes softly pulsating.
Then I get terribly excited because as it changes direction to come back the same way again, the red lights seem to my poor eyesight to be forming a triangular shape. Of course, I think UFO! Except sometimes I can hear a buzz that sounds very much like it might be a far off helicopter, so no. It's a helicopter.
I watch these lights going back and forth and back and forth, and I'm tracking it's movement between the trees on the park in front of my house, and I figure the chopper is circling, looking for something.
But the thing is, the lights change every, say, twenty seconds or so, first from blue to red (all along it), but then they turn green. As I watch it travelling at a consistent speed, sometimes it's flying wider, sometimes over a small area, sometimes climbing higher, sometimes a bit lower. And now the lights are sometimes green, sometimes red, but sometimes I think I can spot white or orange lights amongst the red or green lights.
The "triangle" is not there after a short while. Just looks like a winged object with maybe a light on top. I figure it's the lights long the bottom of the helicopter and one on the rotar. But I watch it puzzled because surely if the chopper is flying in circles, when it is flying away or towards me, I shouldn't be able to see the length of it?
I watched for three fags, but it doesn't do anything else other than I've stated. I got cold. Went up to first floor lounge (townhouse) to look out of balcony door, it's still doing its thing. I go to get this phone from my bedroom to take a video, but it's gone now.
Sadly, I don't think it was a UFO (desperate as I am to see strange lights in the sky), but I'm still curious about the changing light colours. Anyone? I'm guessing this was a police helicopter searching for someone (but no searchlight, so infrared?)
