One video or podcast worth your time is Richard Dolan’s “UFO Crash Retrieval Claim in 1958” discusses a letter from the leading UFO investigator to the Lorenzons that details the strategy of the Brazilian military on UFOs.
It is virtually identical to the US Majestic Crash Retrieval manual—and the Brazil data was documented in 1958.
Current government officials are trying to erase very well documented history that goes back many decades.
The legacy crash retrievals are the key to the kingdom.

Dolan is one of my favorite because he understands how the military, MI complex, and IC operate in opposition to the people re: this subject (and others).
