UFO Sighting in Tampa, Florida on October 2nd 2015 – A smoke trail, or chemical trail in the sky, seen the same thing on the net. Looked like warp drive or worm hole

Standing at work with another coworker when the coworker seen something in the sky. I tried to take a video but I was not quick enough, but I did get a few pics. This event was seen by about 10 or so other employees. It looked like what I have seen on YouTube it started with a narrow chemical like trail and it coned out then as if a secondary booster kick in and then it disappeared
