That's what I heard too, that there was some imminent threat, likely nuclear/dirty bomb. Someone identified one of the drones as a general atomics drone of some sort a little over a week ago. The videos that don't make sense to me is the ones where they are seen in groups of 4 or 5's, those are definitely not commercial planes similar to ones being posted over and over, those seems like planes/helicopters, these don't show up on flight radar for example. Either way somethings going on and they aint telling anyone, not even local governments, which doesn't help.`
edit: surprised no one has tried shining a very strong lep flashlight, they go pretty far.
