During the summer of 2005, a bright sunny day, I was driving on I-95 at approx. 3:00 PM in a northeasternly direction coming from New York City and headed towards Connecticut state when I saw a short white plume of what appeared to be like the exhaust of a military jet fighter of some kind at extremely high altitute. This is nothing unusual, but it caught my attention because I thought that it was at an extremely high altitude. I remember thinking that this jet had to be flying at least 70,000 - 80,000 feet up in the sky. (this is only my guess, I have no idea how high it was flying) I couldn't see the plane just a short white stream in its wake. This jet, what I thought was a military jet, was flying in a westernly direction, it then made a sudden 90 degree turn now going north and up. I could clearly see the perfect "L" shaped white plume and I thought, "Wow, this could be my first UFO sighting" It then just disappeared. I never gave it another thought until now that I decided to check your web site for the first time and I see a lot of reports from a significant number of people, but compared to other reports, my story probably means nothing.
