Flight 77, the supposed plane that hit the Pentagon on 9/11 was a Boeing 757. It is the same plane that President Trump flies in.
A Boeing 757 uses one of 2 different engines: Either a Rolls-Royce RB211 or a Pratt & Whitney PW2000
Here is a diagram of a Rolls-Royce RB211. It says the opening of the turbine of a RB211 is 84.8 inches in diameter. (7 feet)

Here is a photo of President Trumps plane (757), look at the size of the opening of the plane turbine and the person standing next to the plane. Look at the center hub of the turbine, compare its size to the person standing next to the plane.
Here is a photo from the Pentagon on 9/11. Look at the round object behind the person on the left. That is the center hub of a turbine from the object that hit the Pentagon. Notice anything wrong?
It all so obvious people just want to believe the lies because the truth is horrifying.
I suspect it is the other way around. The truth is so...mundane. It is depressing to think that so much damage could so easily be accomplished by commonly used technology. It is all a matter of evil intent. They need the lies to amp up their adrenaline over the possibility of a PLOT to use advanced weaponry. Well, they used a modern airliner. What more advanced weapon did you want? (This was not a new idea. https://en.wikipedia.org/wiki/Operation_Aphrodite.)
I ran into this psychology many years ago in the context of a discussion over the potential for a nuclear weapon being somehow smuggled into the United States and detonated. I thought it was a fanciful idea and proposed a method to achieve the same result with conventional explosives and simple massed concentrations, to be set off remotely. No one would be the wiser. Nuclear technology was not necessary. But nobody worried about that possibility...and the whole prospect was unlikely for one simple reason: the inability to keep such a project secret. So, I realized that technology wasn't the issue. The only issue was operational...and the inherent lack of centralized control.
