Circular orange flame came overhead from the west of Aberdeen heading east. It just past when the orange flame went out and the object turned a a very dark gray colour, sort of triangluar in shape. It seen to float to the ground at the speed a parachute would decend. I lost sight when it dissapeared behind some trees.Exactly the same thing happened 5-10 minutes later, the same course, it stopped in the same place and decended at the same rate as before. I think it must of landed about 1 mile from where I saw it, I guess right in the centre of Aberdeen.My Wife and 2 neighbours also witnessed the first sighting.I also have very short video and poor quality photos of the object.
