According to FOIA documents recently released.
The Mutual UFO Network (MUFON) releases its full report on the Stephenville sightings of January 8th, 2008
Radar data obtained by MUFON confirms that there were Unidentified Flying Objects (UFOs) flying above Stephenville, Texas, January 8th, 2008, just as many eyewitnesses had reported and which made headlines worldwide.
MUFON's analysis of the radar data obtained through freedom of information act (FOIA) requests to the National Weather Service and the FAA show that unknown flying objects were on a direct course to President Bush's Crawford ranch and were separate from the known F-16 jets the same radar data confirmed were flying in the area that night.
The unknown radar targets, which did not have required identification transponders, exhibited strange flight characteristics beyond that of known civilian or military aircraft.
So there, put that in your pipe and smoke it.
