Ufo's don't matter for a couple reasons. Number one if they are actual aliens and they've been visiting us for all this time they haven't done s*** to help us so discovering the fact that they're aliens visiting visiting us makes no difference. Number two the 90% chance these are all electric flight things that were researched starting in the 1950s whose phenomenon are well known and were kept classified because putting a high voltage charge on an aircraft's Hull enables it to make radar waves bend around the aircraft rather than bounce back so it has good stealth characteristics. This stuff's all been studied to death on the internet starting at least in the 1990s and the old news groups and Yahoo groups there used to be tons of information about all this stuff by amateurs who replicated making things fly just with high voltage charges and no propellers and no jet engines or anything like it. It's quiet it makes a hiss at sometimes makes a high voltage blue glow. The phenomenon as well known and little kids have replicated it for science fairs. so frankly if you're all excited about the fact that something is flying without propellers and without a jet engine and you just can't imagine how they can do that. it's very well known and it's the same thing that drives those electrostatic air filters that use no moving parts to ionize air and move it through vent. Exactly the same technology. T Townsend Brown was really the most well known person who researched all this stuff and he was doing it back in the fifties incidentally on the island of Catalina where some of the best UFO sightings were ever filmed in the 1960s.
