Popular theory of explosives used in the towers.
The most popular theory is that explosives were used to bring down the towers. However, no evidence or residue was found of explosives in the wreckage. Many theorists say that the towers came straight down like an organized implosion. However, these towers spread out as they collapsed, taking out a large area.
The towers collapsed due to stress and heat from the plane crashes.
Many theorists say that jet fuel doesn't burn hot enough to melt steel. However, most of the fuel burned off in the first few minutes during the initial explosion, igniting everything else in the towers (papers, desks, carpet, bodies, curtains, etc). This produced a fire hot enough to weaken the supports, causing the towers to collapse.
Building 7
Many believe that Building 7 was controlled demolition since it wasn't hit by an airplane and still collapsed. However, the debris from the collapsing North Tower fell into the base of the tower, igniting fires near the lobby.
Helicopter view shows damage going up many levels.
Upon seeing the damage and realizing it couldn't be saved without risking more firefighter lives, emergency workers were pulled from the scene and it was allowed to burn and collapse on it's own. It couldn't be salvaged.
Truthers say something other than a plane hit the Pentagon
However, three cameras caught the plane but since they were security cameras pointing to an open lawn, of course they would be low resolution. Further, many people saw a jet hit the Pentagon, with the plane clipping several lightpoles on the way in (one lightpole was clipped and smashed onto a taxi driving on the freeway as the jet screeched overhead: http://i.imgur.com/zPvl42i.jpg
The video took one frame every second. The plane hit the Pentagon at 530mph
This means that the camera only got a glimpse of the jet as it sped into the Pentagon. Within 2/3rds of a second, the debris shot 300ft through several rings of the Pentagon. Since the camera was taking a frame a second, it was pure luck it caught anything at all.
Many theorists say that there was no plane debris at the Pentagon, hinting that a missile hit it.
However, the plane hit the Pentagon at such high speeds that there were pieces of it all over the place. Parts of the fuselage were found outside (one guy arriving at the scene found part of a human spine on the lawn just outside the impact zone) but most of the debris shot through the building.
They found the plane, it just wasn't intact
Conspiracy theorists say no plane was found. However, lots of debris was found. Parts of the engines, rims from the landing gear, a tire from the front landing gear was found at the exit hole where the debris punched out, some seats and luggage, data recorder (but too damaged to get any information), and the bodies of all passengers were found.
Many theorists say that the hole in the Pentagon was too small for a jet.
However, the plane hit at an angle and unlike the WTC, the plane hit a reinforced concrete wall. The wings essentially disintegrated on impact, with most of the body of the plane shooting into the building: http://i.imgur.com/nVSAQYF.gif
The plane hit very low to the ground, further making the impact hole difficult to see.
The plane hit the first and second floors of the Pentagon. In fact, the plane was so low the left engine actually scraped along the ground and left marks and the right engine hit a generator and knocking it over.
Theorists say that most plane crashes leave debris, unlike Flight 93.
However, Flight 93 crashed different than other planes. Most planes are crash-landing (meaning that they crash at low speeds and shoot horizontally along the ground to minimize damage). However, Flight 93 nosedived into the ground at 580mph. Most of the debris was buried deep in the earth and scattered around the site. One of the plane engines was found 20ft below ground.
Most of Flight 93 was found
Unlike the other planes, about 90% of the plane was recovered, but the biggest pieces were the size of a suitcase. Both engines were found, the intact Black Box, parts of fuselage, pieces of luggage, seats, etc. They found remains of all passengers, but only about 20% of the original mass was found. For example, instead of finding the body of a hijacker, they found part of his scalp. The rest was consumed in the crash and/or buried deep below ground. But they found remains from all passengers and hijackers.
Theorists say that Larry Silverstein (owner of the WTC complex) ordered their destruction to bank on the insurance.
Larry purchased the WTC complex in the months before 9/11 and took out a major insurance policy on them. Many people would find this suspicious. However, when you buy a new car, do you not buy insurance for it in case something were to happen to it? After all, the WTC was previously attacked by terrorists so insurance against terrorist attacks on the buildings you just purchased isn't suspicious, it's logical.
Larry Silverstein lost money
Theorists say that Larry profited off of 9/11 to make billions of dollars. However, he had to pay for the new World Trade Center (which he still owns) and it turns out he needs to borrow money for that because he used all the money to build the new towers. He didn't make money off of 9/11, he lost money.
Theorists say most of the hijackers were found alive in the months after 9/11
However, this isn't true. Many of these hijackers had common Arabic names, much like John Smith is a common name in English language. If an American terrorist did an act on a foreign country and was named John Smith, many of their media would say that there is still a John Smith living in America currently. Further, if any of these hijackers are still alive, why didn't any come forward to clarify the issue? (ex: Mohammad Atta coming forward to say that he didn't pilot the plane that hit the WTC because he is still alive)
Theorists say that holograms hit the WTC
This is based on several videos of Flight 175 hitting the south tower and sometimes the wing appears to disappear. However, this was due to reflection and refraction. The bottom of the wing reflected and was similar in color the sky above, making the wing look like it wasn't there (and therefore a faulty hologram)
Plane debris was found all over the area
No holograms hit the WTC. Plenty of plane debris was found. This picture of an engine from the second plane was found several blocks north of the complex. Other debris were landing gear, engine parts, pieces of fuselage, body parts and a couple bodies still strapped in airplane seats.
Many theorists say that the calls made on the planes were faked since it's difficult to make calls at that height.
However, of the many calls made on the planes, only two were made from cell phones (those calls were dropped within seconds). The rest were made on the planes air phones which were designed to receive calls at that height. (this picture is a message of what passenger Brian Sweeney left on his wife's answering machine three minutes before his plane was crashed into the South Tower of the WTC)
Theorists said the government faked those calls
However, in calls made by passengers, they gave personal info such as the combination to their safe, calling loved ones by their nicknames, saying where a certain object in their bedroom was, and other personality traits that only the original person knew.
"these cut beams are evidence that thermite was used"
Conspiracy theorists say that 'Super-Thermite' was found in the WTC debris, using this picture of sliced steel beams as proof. However, these cuts were made during clean-up (cutting large pieces of the remaining debris into small pieces for easier transport) which explains why they are near ground-level.
