This one is not a UFO as can be seen here – http://thehoaxkiller.com/forum/index.php?topic=39.0<br /><br />If you go to the Golden Knights website you can see also that they are training at Homestead Florida at this time. The photo in the video shows parachute shaped lights because that is what these are.
Have seen something similar to this is PA. <br />That was explained as military flares. Flares lunch up then parachute down, and because they were lunched at the same time they take on a formation based on wind patterns. Anything not confirmed is a UFO, so I guess you could check REAL.
