It is not that hard to point at something, flying is actually easier than driving.
So this "truther" meme (amateurs could not fly those planes into the towers) is a bad one, a weak one.
It seems that a "physicist" has drank the kool-aid without analysis or with too simple an analysis....

A fully loaded 747 (it was a 767-200 they say) at 550 MPH will have 13,710,500,000 J of energy.
That is equivalent of 1330 lbs of TNT
Even a weak structure filled with a non-compressible fluid (jet fuel) will act like a solid. The funny trick of putting a straw through a potato comes to mind. This works "at least for a while".
Assuming the steel skeleton was 4" thick (it was 4" at the bottom of the tower, and only 1/4" at the top, but lets say 4") A plane at 500MPH, is travelling 8800 inches per second. The time required to travel 4" would be .000455 seconds. In that short span the release of the energy of most of the 1330 lbs of TNT would easily be enough to at least sheer the connectors that bolt the steel together, and even enough to punch right through that steel even if it was a solid 100' length.
The energies of fast moving objects is amazing. Why do you think even small space rocks blow up "Like an atomic bomb". Please enjoy this asteroid calculator that I provide free of charge, I built it after the Russia explosion. Scroll down a bit
They were terrorists, they were found out via intelligence and allowed to carry their plan. The
And of course the planes themselves and their fire wouldn't bring down the buildings, so they were rigged with explosives.
Also, my discovery, they did mini-nukes in the basement for 2 reasons:
1) to make room for the buildings to fall into to avoid knocking down even more adjacent buildings
If they had knocked down a bunch of adjacent buildings, the owners, lawyers, insurance companies and engineers would be taking a serious look at what really happened.
2) to shake and bake and make sure the whole mess came down.
USGS took around 30 detailed samples all over the area, my expertise in radio-nuclides let me easily see that their testing showed levels of radionuclides that were hundreds of time more than naturally occurring. AND that did not come from the granite stonework, it doesn't work that way, the radionuclides were from fresh fission, not from a granite like decay chain.
And they thought it important to also "attack the military" attack the pentagon, but they were fresh out of planes, so they used a cruise missile.
There fixed it for ya.
building were leased to Lucky Larry, because the government is self insured so why not throw a few billion to a fellow jew, while avoiding the billions it would cost in asbestos and lead remediation and demolition.

The object sure doesn't look like a 757 flying 3 feet off the ground. Plus, as a pilot, a stunt like flying 3 feet off the ground in a city would put the mission in jeopardy on the slightest error. I would fly into the center of the building, coming down on it, and that would do more damage too.
There are Deniers who say there were NO AIRPLANES involved in any of this. Bullshit. The towers were hit by planes, the other 2 are likely fake.
