there is no evidance to sugest if there is alien life it has been here. I would not be suprised if most sightings of any real value are not military.

If you research you will see NASA did crack gravity, there is a way to shild you from it so you are imune to high speed turns.. google NASA and anti gravity programs. you will see in the 60's they were big on it.. then declared it was imposible and close the project.

also research some odd side effects of super conductors when you spin them at extreamly high speed, and you may link two and two together..

so there is some freaky aircraft out there, but its not from another planet.

if it was, they would have made contact.. or be watchign from a distance.. why would you fly over a barn for? or hover over a city, or turn cars 180 degree's.. its just hippy talk..
