I am certainly not even close to an expert but I am not buying that the lights belong to a formation of jets. Mainly because unless you are in a display team etc, there is no valid reason to be flying such a tight formation at that altitude. Pilots do not take such risks needlessly. From a military standpoint, you don't bunch together because if a missile etc hits one of you, it will probably take you all out.
Also, I doubt even the best display teams would fly such close formation at night. I can see no justification for such a formation. I could be wrong of course and feelings are not facts, but nevertheless I do feel that video shows a single object with multiple lights.
Whilst on topic of vids, I encourage everyone to check out a post I did the other day, featuring vids from
UFO sightings on AnonymousFO.com - UFOs, alien and ovni, news, and reports. Find out what are ufos - the last couple had some stunning videos.
