Do you have a top secret clearance for Area 51 and the top secret facility in Ontario? If not, then how would you know? I believe that what I saw about the technology means they are trying to perfect it, so our military can use it, but it has issues.
People choose what they believe, and I do not believe in little green men, or Aliens from outer space, sorry.
Use the fallacy of the undistributed middle much? ... What do ‘little green men’ have to do with a discussion of how one can fly through the air? And as to a clearance for area 51, is that what you have been programmed to believe would be the site of all advanced tech? ... Lockhead and Northrup have facilities for secret research at sites in NV, CA, and elsewhere. And that I do know from experience.
