I came back from a visit to my parents and drove across the n279 near the village aarle rixtel (not far away from he militairy airfield at volkel).As i drove in souhern direction across the n279, i saw a still light in the sky on the east side of the n279 at the height of the bakelseweg. at first i thought it was face fraud and that it would be a plane flying straight to me, making it seem to be still in the air. as i got closer, i began to doubt more because it seemed to be quiet in the sky. then i also saw flashing lights on the side, giving me the impression that it might be a helicopter. but at one point the vehicle was almost perpendicular to the car. i reduced speed (turned out that there was a car behind me witch nearly bumped into my car) and opened the window to better sense and was surprised that the vehicle was triangular in shape, estimated 30m long, at an altitude of (estimated) 300m to the darkness of the night and was complettely sillent. because i could not stop, i spent about 3 minutes the first opportunity to reverse the car. once again, back to the place where i had seen the vehicle above me, i saw that it was moving quite slowly north-west towards aarle rixtel. i have seen many airplanes but never something like this. perfect triangle, verry slow moving and completely silent. later on i saw a documentary on youtube showing a movie in which, in my opinion, exactly the same plane was shown. attached the link to the movie. it can be seen after 1 hour and 4 minutes. https://www.Youtube.Com/watch?V=a02hffrqigm. i also reported the sighting at the dutch website www.Ufomeldpunt.Nl (date 24 november 2016) and tried to report it at the volkel airfield but never did succeed because i never got a call back.
