His name is Sam Eckholm and used to work for the U.S. Air Force as the publicist for the Raptor F-22 demonstration team. Now he is a "content creator." But he appears to have stayed in touch with his military superiors because he gets access to things which are as crazy as they are fascinating.
I have featured Sam once before (and I will again), but this is his latest video.
In it you will get unbelieveable access to what happens to launch a Atlas-5 rocket and you will learn all about "The Guardians."
