There are objects in the night sky that cannot be explained by any known source. These UFO objects, according to the best expert on spotting them, are best viewed within the first two hours of complete darkness after sunset. If these objects, the expert reasoned, are flying at night visibly cloaked, they should still give off heat signatures. They do, just as these two did on Sept. 12, 2010.
