TR-3B Astra is a secret development of US tactical reconnaissance aircraft. Most often it is perceived as a triangular UFO due to the fact that the power plant of this aircraft is essentially a generator of a powerful magnetic vortex field and the light flux periodically emitted by this generator is perceived by outside observers as unearthly and inhuman. This creates an effect of incredible lightness of the ship and allows it to maneuver and absolutely exceed by technical characteristics all built-up aircraft. The cockpit TR-3B Astra, surrounded by a kind of ring particle accelerator, which is ahead of all conceivable technology of our time. The main goal and peculiarity of such an installation in the generation of a powerful magnetic vortex field, which partially (up to 90%) or completely, neutralizes the effect of gravity on the mass of the apparatus itself. The "Astra" pilots are able to safely transfer the acceleration to 40 G, as the effect of 89 percent loss of gravity
