an intentional crash-landing of the remotely piloted aircraft into several steel structures set up on the bed of Rogers Dry Lake at Edwards Air Force Base to breach the fuel tanks in the wings.
In addition to the fuels research, NASA's Langley Research Center conducted a structural loads measurement experiment that included having instrumented dummies occupy seats in the passenger cabin. The plane was also instrumented for a variety of other impact-survivability experiments, including new seat designs, flight data recorders, galley and stowage-bin attachments, cabin fireproof materials, and burn-resistant windows.
During the 14 flights, the Boeing 720 was controlled remotely by a pilot at a ground-based console for 16 hours and 22 minutes, including 10 takeoffs, 69 controlled landing approaches, and 13 landings on the abort runway.
The Controlled Impact Demonstration marked the end of FAA attempts to order airlines to use the anti-misting additive in fuel for airliners. Although proponents argued that the modified fuel prevented a hotter, more catastrophic fire during the test, FAA requirements for the additive were cancelled.
The demonstration underlined an often-overlooked aspect of aeronautical research. Although the small-scale ground tests had indicated that the anti-misting additive would be effective in reducing post-crash fires, the full-scale demonstration in a real-world flight environment showed that the modified anti-misting fuel was ineffective in reducing the propagation or intensity of fire.
Cameras inside the airliner showed the crash dummies being shaken and small panels falling during the crash-landing, although the seats remained attached to the floor. The new seat designs, flight data recorders, galley and stowage-bin attachments, fireproof materials and windows were tested under real-world conditions. Research data from the project in these areas yielded new data on impact survivability that helped the FAA establish new rules regarding fire prevention and fire-retardant materials.
Not quite 19 upon receiving his wings, he flew TBM Avenger torpedo bombers from the carrier USS San Jacinto in 1944. It was said that Bush was “one of Grumman’s best customers,”
briefly flew Convair F-102 interceptors while serving in the Texas Air National Guard from 1968 to 1974, but didn’t see combat.
The first “drones” were actually balloons, first deployed by Austria in 1849. They came equipped with long copper wires that operators used to remotely trigger bombs, which would fall and explode on impact. These didn’t quite catch on, for obvious reasons—they floated in any direction, including back towards the way they came. Other inventors drew up plans for remote-controlled dirigibles that never got off the ground (as it were).
But in the 1910s, the US began hooking up unused warplanes with autopilot systems that the military could control remotely. These systems relied on new tech that had just come online: The Kettering Bug, developed for the Army’s Air force just before World War I, used gyroscopes to keep itself stabilized. Pressure sensors kept the aircraft at a certain altitude, while its operator could calculate how far it traveled by keeping track of the rate its propellers were rotating. These “aerial torpedoes” were still fairly rudimentary, though—they could only travel in a straight line, which made them useless for more targeted strikes. “You’d launch them into some area, like a city, where they’re bound to hit something,” Everett says. They were never actually deployed.
Later, operators wielding joysticks could actually steer planes from afar. Essentially, whoever was controlling the plane would use a transmitter to send radio signals to a radio receiver on the plane, which would control a motor that turned the plane’s steering wheel or pressed flight-control buttons. The controller had to fly behind the drone itself in a mothership, because the connection petered out after a few miles.
These first systems were, unsurprisingly, fraught with problems. “Control systems were being developed in a very hurried fashion and they were very new, so they didn’t perform very well at first,” Everett says. Radio interference meant choppy connections, which made the actual planes difficult to direct. Traveling in motherships posed a tactical problem: They were slow, large, and obvious—in other words, easy targets. And operators who rode in the motherships had a hard time actually controlling the drones, since they were observing from afar. Brand new TV sets, installed in the planes in the late 1920s and early 1930s, helped, but they still weren’t perfect. “The picture quality wasn’t that good even when the sets were working correctly,” Everett says.

Drones are nothing new, they have been used since the begining of aviation :

That remote control has always been a possibility since it is a decade old tech.
In 1984 or 2001, the technology for remote operating a device through radio-waves had greatly improved in comparison to the WWII-era.

So far I don't have any reason to consider that the planes were remote-controlled, sorry.
If the planes were empty, where are the passengers who boarded them ?
If the planes were remote-controlled, why did they need to put highjackers in them ? They could have remotly de-presurize the cabine, kill everyone on board and then flight the plane wherever they would have wanted.
Not to mention : why did flight 93 'failed', when the others 'succeeded' ?

My guess is that you are likely to dismiss whatever proof anybody could submit you ...
Let's put it in another way : Do you have any proofs there weren't any passenger in flight 93 ?

There were people in flight 93 and it crashed in the middle of nowhere ...

Why don't you believe there are someone onboard these planes while carefully avoiding any statement about flight 93 ...
Double-standards ?
Do you take the moon landing for granted since you weren't able to double-check by yourself ?

You need to ask yourself the right questions at some stage.
Why would there be corpses in flight 93 and not in the others ?
After all you can push your 'skepticism' into considering there were no corpse as well in flight 93 ...
The crash scene of flight 93 made it more convenient to retreive human remains than the WTC or pentagon, that doesn't mean there weren't any in theses either. Or you can consider you were 'lied to' about the flight 93 corpses as well ...
The passengers were taken somewhere and disposed of.
No man would let someone with a box cutter kill innocent lives. Common use common sense.
Can you provide proof that there was anyone on the planes that crashed into the WTCs? Proof as in not a statement but proof as in a medical examiner confirming the bodies.
