For any interested lurkers, here's the link: UFO Crash Retrieval Claim in 1958 | The Richard Dolan Show.
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).
Just a repeat from earlier in the thread.
This is the government manual for crash retrievals. If you compare this to the Brazilian government approach you will see it matches in every detail.
Imho this is very strong evidence that the manual is legit.
