My dad told me of seeing some fighter jets following a light in the sky near Lemore airforce base just a few years ago. He figured it was another jet, but then the light did, what seemed to him, an impossible turn, then took off north at an incredible speed. The fighter jets followed, but not even close to the same speed, as the light was no longer visible a few seconds after it turned direction due to its apparent speed. What to make of it? Who knows.
