Eleven objects over Manhatten for nearly 2 hours.At approximately 1600 hours on the 8th of September I witnessed a number of UFO's with another person. We were in Central Park in NYC and I was laying down in the shade looking straight up in to the sky. I noticed one object that looked to be circular and white, I thought it was a satellite or maybe a planet. I didn't think much of it until I noticed that it had not moved for several minutes. I pointed the object out to my friend and asked if it could have been the planet Venus since sometimes you can see it during the day and it obviously was not a satellite since it had not moved. As we were both discussing it we noticed that it had started to move. Then my friend pointed out another one in a different part of the sky. As we looked around we started to see more and more. We watched as the slowly moved in different directions and at one point three of the objects formed in a shape of a triangle (probably several miles apart) and then slowly moved back into a straight line and then went in completely different directions. The most interesting event was when one of the objects looked as though it completely changed form and turned from a sphere into a longer thinner object. This object moved at a high rate of speed across the sky in a movement that could most closely be described as "sperm-like." Due to it's speed, this object was only seen for about 45 seconds before it moved out of sight. The rest of the objects very slowly moved apart from each other or too high for us to see. The final talley of the objects was eleven.((NUFORC Note: We do not know what the witnesses observed. We spoke with him over the telephone, and found him to be serious-minded and quite credible. We encouraged him to try to get a photo the next time he watches something unusual for 1-2 hours. PD))
