Advanced Antigravity Stealth Technology That Has Been Hidden For Years

This video is an overview of black budget and classified aircraft that have been secretly developed. overviews possible propulsion for the SR75 to be an air turbo ram jet “cold turbine” technology. Overviews relationship and letter exchanged between Ben Rich and John Andrews including if Ben Rich used the term “snowbird” he would be in jail. Overview Magneto-Hydrodynamic Drive (MHD) (utilizes electric and magnetic fields) no moving parts probably propulsion system for “snowbird” speeds above Mach 20.
Review Caltech Seismic reading that picked up a series of air quakes every Thursday with the exception of Thursday Thanksgiving day. Speculates that Snowbirds mission is to act as a nuclear proliferation monitoring aircraft.
B-2 Bomber’s electro-gravity propulsion system stating that (1 out 3) B2 bombers are “antigravity” TR3B and Anti-Gravity Triangles
