The whole incident made me think of a teenager that has gotten his fathers car and was just out seeing what that baby could do.Object looked like a Satellite traveling from northwest to southeast. Object began a gentle turn toward the east and exhibited an increase in velocity for approximately one or two seconds. Object then turned sharply north and increased velocity again for about one half to one second at that point the object appeared to dive or decrease at a very steep angle, straightened out to a level trajectory for a short time and again appeared to initiate a dive. During the second dive the object left a trail behind it much like a meteor or falling star. The object then seemed to clime back to its original altitude and very abruptly change direction back toward the south, southeast. While traveling at a high rate of speed the object zigzag east to west while continuing in its overall south-southeast direction. The whole incident made me think of a teenager that has gotten his fathers car and was just out seeing what that baby could do.((NUFORC Note: Satellites probably would not be visible at 02:40 hrs., depending on their altitude. PD))
