Radar doesn't see mirages only solid objects. Radar can see through clouds. could reflect off ice but ice doesn't move at mach 2 or above in a horizontal motion. could be your wrong... ever crossed your mind. With all the black budget programs out there you don't think our or other government are trying new propulsion's out (?) What was the saying ? "The simplest answer is usually right"! If I'm driving down the road and I say I seen a truck or a car then I'm pretty sure it was what I said it was because I've seen one before. So if the pilots say "I seen a CRAFT" I'm pretty sure that's what they saw. Ice or the other things don't rise up from below you and start following you around.nsaspook said:but a mirage might be a good description of it.
