its our tech. you think anything could be in us airspace and not shot down?  they are plasma drones. the tech has been worked on since the 80s.  they use lasers to split ions, forming a plasma, and this acts as a foil which reduces drag by over 50%. it also cushions the vehicle from breaking the sound barrier and the force of that on the drone, and shields from the friction with the atmosphere that destroys meteors and much slower objects moving through it.  this is how all hyper sonic jets current work.  there are videos of people who worked on black out projects in the 90s, and they talk about forming the plasma into a self sustaining wave, at which point it can act as the vehicle and propulsion itself. these are part of our 6th generational warfare arsenal. 6th gen war is the manipulation of space and time for conquest.
