Hover above treeline

Filmed on 16 februari 2016 in the Netherlands.
It was a clear sky and allot of activity.
This video is one of the many captures i had within one and a half hour time.
Like the craft in this video.
It suddenly appeared above the treeline and hover there.
I could easily filmed it, so i started to make pictures.
I put the camera on the stand to make 10 pictures with half a second delay time.
The first time was on 30 optical zoom, then i zoomed in to 50 optical zoom and made another 10 pictures.
Right after it i started the video, and filmed it until it slowly fly to the right with a dimmed light.
THis red craft is the same craft what appear with a bright light randomly anywere.
