Seemingly impossible reverseAlthough years ago, my wife, stepson, and I were camped very secluded on a dark summer night at the north end of Pyramid Lake with no fire or lights in camp when my stepson and I spotted a satellite traveling south to north. I have seen many satellites and was sure thats what it was when suddenly it did an immediate reverse. Not a turn, but an immediate reverse and maintained the same speed! I've always been curious about it and wonder if you have had any similar sightings reported. I know of no aircraft or spacecraft that could achieve such a maneuver. Please confer.Thank you PS-saw an ad on tv for mufon and got me thinking about it again((NUFORC Note: Witness indicates that the date of the event is approximate. PD))
