this was quite eery to observe not knowing if it was a drone or what it was. The white mist that appeared to spray out was concerning.

Remarks
The light appeared to be coming toward us and was orange - looking like a light from a plane. It then appeared to start to change to a bright white light and leave a large trail of white mist. As the cloud of mist grew bigger the white light continued to get smaller and eventually go out. There still appeared to be something left in front of the mist cloud that not longer was lit but slowly disappeared.
