I saw 9 egg shaped orbs in the sky, which than dissapeared and moments later three military jets flew byOn Sunday February 8th 2009, at approximately 14:30pm in the afternoon, in the town of Erin, (Washington County) WI which is about forty miles northwest of Milwaukee, WI. I was outside alone enjoying the warm weather. The sun was shining brightly and there were no clouds in the sky. I was looking up at the sky in a northeast direction with my back to the sun. I saw what looked like a flock of white birds flying in an oblong circular formation around one single bird. As this is nothing strange to see in the country, I started to notice that the "birds" had no wings. Also, they were flying much too high to actually be birds. After closer inspection, they now appeared to be silvery white egg-shaped orbs. This realization happened within the first ten seconds of seeing them. As I looked closer, I could tell that the central "bird" was much shinier than the others. Then they broke their formation and started to dart out in all directions, flying around in circles on their own. Each craft circled and stayed relatively within its own zone. This happened about 40-50 seconds after I had begun watching them. At this point, I counted nine of them, including the shinier central one. Then they began to move in a different series of maneuvers. They began to spread out more; flying closer back to the center and then farther out again. Then, in another change of maneuvers, they started to scramble all over the sky. At about 90 seconds into my sighting, they started flying in what seemed to be straight lines jetting out from one another and making very abrupt and sharp turns.At this point, I started to think I should run and get my camera, but I had become so amazed by what I was seeing that I could not tear myself away. I quickly turned in a circle to view 360 degrees of the sky around me in case there were more of them. I then quickly turned back and started to watch the crafts. They started looking farther and farther away from me. This was about two minutes into my sighting. At which point, the one that was farthest to the left disappeared. Then, about five seconds later, the one farthest to the right disappeared as well. This now left seven egg shaped orbs to remain, still looking very white and silvery gray. Then the orb that was closest to the bottom of their dissassembling formation disappeared. Then the two that had been above the center one disappeared. While the last four orbs remained, three of them made a formation in the shape of a pyramid, or triangle with the point on top surrounding the shiniest one in the center. Suddenly, all three orbs in the triangle formation disappeared. The only one left, the one that seemed to have a metallic almost aluminum shine to it, darted left, then right, then down, then up, then back to the center point. Suddenly it just disappeared.As I stood still staring up at the sky, I then started to realize that I had seen something very out of the ordinary, and that I might have just witnessed a UFO sighting. At that point, roughly two minutes after the last orb disappeared, three grey military jets, coming from the west, flew by in a spread out formation all flying in the same direction and at the same altitude where I had seen the orbs. The middle jet flew right into what could be considered the center of the orbs’ flight pattern. The jets also appeared to slow down a bit once they got to the exact area the orbs had been. Once the jets flew by and I could see where they were in the sky, I gauged that their altitude must have been somewhere between six and ten thousand feet. It is also important to note that all three military jets were letting off huge chem trails. After a few minutes the sky filled with long, thin and spreading clouds. I saw birds were now in the sky and I could tell that the wind was again blowing.It is not strange to see any airplanes fly by at a very high altitude, or see one of the many small ultralites or hobby planes flying at a low altitude. After living in this area for the last 20+ years, I have witnessed many varied aircraft on their way to and from the Oshkosh EAA annual Fly-In as well as normal air traffic. The only times I have seen low flying military jets in this area is when they are on their way to the EAA annual Fly-In or some other public event.
