Project Aurora Over the years rumoured sightings have become more and more frequent. Photographs of “doughnut” shaped con trails have been taken. The photos show the “doughnuts on a rope” type of con trail that would be left by a craft capable of travelling at such high speeds using “pulsed jet” technology as the propulsion source enabling the aircraft to travel five to ten times the speed of sound. Flying into sub orbit at those kind of speeds this craft could reach anywhere in the world within three hours. http://www.where-is-area-51.com/aurora.html
The aliens helped Nazi technology in WWII. They were light years ahead of everyone else and invented synthetic oil. They will reveal themselves. The Governments know all about it. I once wrote an article for Nexus, conveniently priced at £4.25 by the way folks, and was visited by The Meninblack. Not that pishy film thing but government agents who attempt to silence those that have been "visited".
