What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
It was a light-green light moving across the sky. It was the same size and speed of a helicopter. However, unlike a helicopter, it had no sound and the light was green and not flashing.
Did the UFO do any
strange things like hover and then zoom off quickly :
No. It moved steeadily across the sky.
How long did you see the
UFO for :
00:00:50
-hh:mm:ss
Any additional comments :
I have tried to think of possible explanations. It wasn't a firework because it went too far, too long. It wasn't a fire lantern because it went too fast and there was little wind. I don't know of any military bases in the area but that would seem like the most likely explanation.
