A Mach 20 ship would break the sound barrier and must make a sonic boom or break the laws of physics.
Yes, which means that either a million people around the world including military, air force pilots, and police are crazy and all seeing things or these UFOs cannot fully be in our dimensions and must exist on another plane only partly discernible to us, allowing them to pop in and out of our space and zip about as if inertia did not matter (or at least they are not interacting with it), perhaps by slipping out of time, which would also allow them to travel great distances by changing the constancy of time between us and their ship.
