Date of sighting: September 26, 2015
Location of sighting: Over St. Louis, Florida, USA
Missouri - 09-26-15 - I was flying on SWA flight 3357 on Sept 26, 2015 and had just taken off out of St. Louis to Florida. About 15-20 minutes into our flight I noticed what I thought was another plane and all of the sudden whatever it was did a 180 without losing altitude or speed. I can only see two contrails but no object. I was shocked as I'm a flight attendant and have never witnessed anything like this before and my husband also saw it and he flies every week for the last 25 years and has never seen anything like it. I have shown many others, commercial pilots included, and they also have no idea what it could have been. The stills I have included are stills that I took from pausing the video.
