I thought the best way to film a UFO was to film normal air activity whenever possible. I filmed a Helicopter going North, then moved to a chemtrail, which was faint. A black orb appeared and disappeared, I later found when looking for the chemtrail in the film. I think I may have seen it while filming, don't know, a lot was going on at the time. After filming the orb, The helicopter returned, but this time heading south. I filmed the Helicopter as well.
