Damn that’s some crazy stuff. Given the sonic boom you speak of below I don’t think it’s technology from outside this planet. I think sonic books are from breaking the sound barrier yes but the crafts that are truly from another planet are probably above technology that would make noise like that. I forget the guys name who spoke about it but one of the guys that leaked info about Area 51 was saying he worked on a spaceship there and it bent gravity. That type of stuff is truly insane, I think this shop here was top military technology they were messing around with.
