Wrong on all counts.
The video you posted was recorded by Tom King while he was at Steve Blonder's prior residence. King filmed the exact same event that Mike Krzyston and Chuck Rairdon filmed at roughly 10 PM in the evening. The video you posted does not last an hour, and that's because the flares in question weren't in the sky for over an hour.
You need to understand that there were two events that night. One event was at around 10 PM and that is what most of the footage depicts. This event was flares. The other event was earlier in the evening between 8 and 9 or so, and there is only one piece of footage of that event which was shot by Terry Proctor.
