Original source for the two vids including the helicopter part please.
That's too convenient to fake that footage when you're given no frame of reference. I know my city pretty well and if they caught some of the scenery I could tell glprs more about its legitimacy. Right now, im skeptical of this footage, you can't just call out "DIMENSIONAL STARGATE!!!!" when it isn't even clear whether or not those arent phony and just cleverly edited together.
