Some of the unexplained theories
1. While the rest of the world uses identification to board flights (State IDs for domestic travel, passports for international and non-American's must provide either Green Cards or Passports), a foreign terrorist hijacker was able to board a flight while leaving his passport in his friend's luggage. And that luggage also happened to name all 19 hijackers and their precise motives in carrying out the attacks on the morning of their deaths
2. Commercial airplanes’ frames are constructed with a very light aluminum material in order to make it easier to fly. Theorists maintain that there is no possible way an airplane can do as much damage as it did to the Twin Towers as it did. Theorists believe that missiles or explosives were used to ensure the buildings collapsed.
3. In flight calls were made from cell phones in hi-jacked airplanes. Scientists and skeptics maintain that cell phones could not receive reception from the altitude the planes typically fly at.
Other skeptics questioned a phone call from a son to his mother, in which he referred to himself by his own first and last name.4. No steel structure before (or since) had ever collapsed due to fire. While some steel buildings had burned a long time from fire, none has fallen because steel melts at a much higher temperature than gasoline, other fuels or combustibles normally found in buildings can burn at.
Despite this resistance to high temperature, on September 11, 2001, three of the most advanced steel structures in the world collapsed officially due to fire caused by burning jet fuel and structural damage due to the impact of the planes. This angle may not convince everyone of an alternate explanation for towers 1 and 2, but for tower 7, how can this be explained?
WTC 7 is considered by many conspiracy theorists to be the smoking gun of 9-11, because they argue is no plausible argument that can justify
why a building that had no direct impact by the plane would burn so hot as to cause a first-of-its-kind collapse of a steel structure (aside from the towers hours earlier). Physicists like Steven Jones and scores of independent researchers from around the world agree
