The way some of these objects fly is the exact same way that Bob Lazar stated years ago. That the saucer tilts up and moves forward. As filmed by the naval aviator and released last year.
That the craft is able to create a gravitational field around it. By doing this is can move at much high velocity and not subject the occupants to the G forces that would kill them.
The gravitational field uses an element on the periodic table that the scientific community did not believe existed until just a few years ago.
That's exactly what the kids at the Ariel School incident in Zimbabwe said—the UFO leaned over on its side when it moved away.
