In part 1, Tompkins alleged that Thompson Ramo Wooldridge (TRW), which was bought by Northrop Grumman later, had been building tunnels in the underground for high-speed rail. The tunnel-boring machines they used have anti-gravity device.
He also mentioned that on some occasion the tunnel-boring machines ran into enormous carvens which have already been occupied, and they belong to several different extraterrestrial organisations living there for thousands of years.
In part 2, he talks about a type of medicine developed by TRW back in the 70s that has an effect of age-regression as well as enhancing brain power.
At the end of the show, they also discussed about the allegation of Nazi German setting up bases in South America at the end of World War 2.
It is also good to know that some Air Force generals and Navy generals are supporting the full disclosure.
