UFOs, in the sense that they are the product of extraterestials, are not happening. Much of it is pie pans on a string and meteors.
Any one knows what a meteor is so I think that is
trying to simplify it too much.
Hoaxes with pie panís and camera has probably been done.
but pilots reported UFO,s back in the 1940s and many times
since.
My wife and I saw a solid green light travel from the eastern
horizon to the western horizon in 8 to 10 seconds one time when you heading south in the Mexico dessert.
A jet would take several minutes and a meteor would take a second.
As many have said ... it’s the 5% of sightings that resides outside normal parameters.
