upside down V formation of 9 birght lights on high altitude changed to M formation in less than a secondMy sister lives at the coast, and I went to visit her... we were going out. When I arrived at her door I rang and I looked up to the second floor window. That is the window of her apartment, she mostly opens the window to throw the keys. When looking up I noticed 9 bright lights. There course was WNW. They made no sound. They seemed to be flying very fast and very high, though the lights were very bright. I couldn't distinct if anything was between the 9 lights. There were no blinking lights. It was as if you see 9 sattelites flying over in perfect inverse V formation. During the V formation the speeds of the lights was constant.Then suddenly I knew it weren't just planes or helicopters in formation, cuase the shape just changed to a double inverse V formation!!! The changing of the formation was only a split second, and the movement of the different lights were smooth without one of them crossing onother one. The movement of the different lights wasn't symmetric, the left side of the V moved differently then the left side of the V... .. .. .. .(if this works out this drawing... they moved from the shape above to the shape beneath) . .. . . .. . .The pattern in the movement (!which went very smooth!) was like random. Normally in aviation they have a fixed manner of changing to another formation. Also it happened in only a second time. The way they slowed down and catched speed up again was surprisingly smooth. It wasn't in a way that If they were fixed (in some way connected) so that turning over or changing angle caused it for me to see it as another formation. (I really hope I express myself good here, I'm Dutch :) )((NUFORC Note: The diagrams of the object's two shapes, rendered with ASCII characters, did not survive the transfer from the e-mailed report to the database program. Moreoever, we have no idea what will happen when the report is transferred to the website. In the original version, the object was a V-shaped object, with approximatey 30-40 degrees of angle between the two sides. After the object had changed shape, the three lights, which comprised the "nose" or tip of the wedge, had moved back, so the formation then looked like the letter, "M." PD))
