did the U.S. get information from roswell?

i found this siteUSAF UFO
and if it is real which i think it is then where is the perpoltion system or could it be getting around the same way that the real ufo's do
and maybe the aroura is round and the military wants us to think it is triangular so the other countries like russia thinks it is an alien ufo flying
so post your opinions i am really curious thank you

I for one want to think that the triangles are ours...I would be unhappy the gov doesn't think the world is ready for full disclosure..We can all get a grip on somekinda "anti-gravity machine"...We won't all go a running at the sight of some silent "flooting house sized ship"...espesially when there is a little US flag on it...Those pics of disk all fly with typical propultion systems..I think the tec is out there being used by us now.....just my 2cents..
