CAUTION, THIS IS NOT A HOAX, THIS IS REAL!!! I woke up at 04.00 AM. Preparing my working day. I had a glimps out of my windows which direct to the hills nearby, where the villages called "Evilard and Macolin" are located 2600 feet northwest, above the City of Biel/Bienne. It was a rainy and overcasted night. There was a triangular shaped craft appearing and hovering fully noiseless at a thousand feet above the City of Biel/Bienne, on the nearby hills in the air. Just above the Hospital. I could clearly see the craft in its full shape and Motion. It wasn't a common Airplane, Helicopter or aircraft which are known to me untill yet. (Btw. I'm a Commercial Pilot. I am well aware of pretty much all type of Commercial or Military aircraft in service). 12 or 14 verry bright pulsating lights shaped on an a triangle, blinding me at a 5 second interval, changing its lights constantly from green to red to white to yellow and back to green, hovered above the forest at the nearby hills, for quiet a long time. Some 15mins or so. At allmost the same height above the City of Biel/Bienne as the Hospital is located.Verry unexplicable and unusual. Normally there's only the Helicopter on its medical missions coming in and heading out. I had a great glimps on it. But I could'nt film it or take photographs of it, because all my electronic devices such as my digital SLR Camera shut off due to interferance of magnetic field and possibly radiation emissions from the craft. I even could feel warmth on my Skin caused by the brightness of the lights. Then, suddenly it climbed ontop of the nearby hills and stopped hovering ontop of the hills for another 2 to 4 minutes. Then it turned around and flew from right to left and back to right on a verry abnormal and incredible amount of Speed which is just not possible for airplanes or helicopters or any other aircraft due to earth's gravitation. After it shot from right to left and back it flew up and away and disappeared at allmost the same Speed as it shot from side to side... it reminded me of the Speed of a bullet from a shotgun. Just couldn't explain what that was... should've been a UFO on its contact mission... nothing else is possible to me. I am not aware if there where any other People who witnessed the occurance and who possibly can confirm the sighting.
