Was taking a video of a dashed chem trail. when i played it back at normal speed i thought i saw something, i went to slow motion that's when i saw it plain as day.I am an ex-airforce crew chief on the f-4 phantom.I've never seen anything move this fast making a turn as it did. when in slow motion it seemed as though it was winged or maybe it was doing barrel rolls. i would change from black to white. when you watch the video at .02 seconds just above and to the right of center you will see it become visible.
