“Trump was likely told little.”
Interesting topic.
Many researchers believe President Trump is “playing dumb” on this topic.
His uncle is a fascinating individual—most likely shared some of the “secrets”:

Now the next clue needs you to fasten your seat belt—this book actually exists:

There are two other similar books written in the 1890s by the same author.
This is a wild rabbit hole...
My uncle passed recently. I had really hoped he would share more before he went, but it was not to be. During his life he did let a couple of things slip - directly or indirectly:
He spent a lot a time at Area 51 and they do more than test aircraft there.
He spoke a lot about the atomic aircraft project - now declassified - and how the building that housed it was the largest single building, in volume, in the world, and they couldn't tell anyone.
The government has Tesla's files. The contents are highly classified. They led to HAARP. Our cell phone network is more than just a cell phone network.
For a while he was an instructor at the NIA or National Intelligence Academy in Fort Lauderdale, near the Executive Airport. I got a tour once. Back in the 80's they had listening devices so small I thought they were impossible. They had a device that could read info off a computer's hard drive even if the computer was off. For fun they would lock padlocks together in a chain and time who could unlock them fastest. I saw a guy unlock 5 padlocks in about 20 seconds.
I remember, when I was a kid, my uncle having an argument/discussion with my parents. My folks insisted on living in South Florida and my uncle was trying to convince them it wasn't safe...that he couldn't guarantee their safety there. Something about the water table. In retrospect, I wonder if my uncle had access to the tunnels and, in case of emergency, could bring some family? And that maybe, because in South Florida if you dig down six feet or so you hit water, there wasn't a lot of nearby tunnel access? I would venture to guess you would have to go to MacDill AFB or maybe the Kennedy Space Center to hit a military place that was on some sort of firmer ground. Those are a good 4+ hour drive away.
