This video looks like many of the other disc shaped objects captured on cellphones and cameras around the world. This could even be the world famous Gimbal disc caught on a person's phone. The military said there are fleets of these things flying around. They can go from a hovering state to instant acceleration so fast you can't even see it take off.
Lot's of skeptics always make this straw man statement.
"With everyone on the planet having a smartphone, where is all the evidence of UFOs"?
That will shut some of them up. I'm sure many will proclaim they're just fake. I don't believe there is conspiracy of people around the planet all faking footage of the same looking objects. Discs, big triangles, small orbs of light, cigars and on and on.
