Don't get your hopes up about little green men from Mars flying UFOs in the Earth's atmosphere. Little green men from Mars don't exist in the first place. And there is no such thing as flying saucers either.
Bill Nye's explanation is the correct one. Remember that Nye was an aeronautical engineer working for Boeing in his earlier life.
Aircraft flying above 60,000 feet are all VFR and do not have to report to any air traffic control facility. Such high flying aircraft will not be squawking anything that the air traffic control people can decipher. However, they will be in constant contact with "home base", whatever and wherever that may be. They will be using enciphered data links, satellites, etc., etc..
Douglass is a long time observer of what goes on visually and electronically in the skies of western Texas. His photographs have frequently appeared in Aviation Week and revealed new designs including, a couple of years ago, what may be the new B-21 flying wing.
Aviation Week has also published pictures in the last few years of the unique contrails of an aircraft that is referred to as the "Pulser". But the people who took those pictures did not see or hear the actual aircraft. The term "pulse" refers to a pulse detonation engine. Lockheed has publicly stated that they were working on such an engine that could be used from takeoff to the hypersonic flight regime. If such an engine is successfully developed, and the project appears to be ongoing, then that would be a giant jump in high speed engine technology.
