104 BREAKING: top defense expert tells me that UFO shot down over Alaska by American F-22 was Chinese “exotic vehicle” that is hypersonic and might even have “anti-gravity technology.” These vehicles can travel at MACH 5.

Mach 5? Ooo-er, thats only high supersonic, hypersonic is escape velocity.
But if its good enough for Buck Rodgers.....
Mach 5 is the start of hypersonic speeds.
Escape velocity is about mach 32 or so.
