First of all. An object in motions stays in motion. When the buildings began to collapse (The top did tilt btw) the mass of weight coming down quickly overwhelmed each floors. As the weight came down the collapse speed would have picked up speed. Secondly. The wtc was built with a framed tube design which means that it was designed to resist lateral forces which means the entire thing would not have tipped over. It would have come straigt down. Thirdly, the air in the elevator shafts and stairwells would have needed to be forced out somehow. The mostlikely spot is the skylobbies, and that is exactly where we see it happening. It happened on all sides of the buildings and both towers. 4th the north tower fell on WTC 7, and severely damaged it. Firefighters on the scene heard WTC 7 creaking, and they saw smoke billowing out of the entire south face. They also reported that it was beginning to buldge. Here is a video about WTC 7 that explains what i am talking about.

Dont forget the way they distort evidence

rapunr- You know nothing about thermite. First of all if thermite existed then the towers would have collapsed very soon after the planes impacted. Second of all nobody has even proven the stuff was molten steel. it was likely molten aluminum (Which does glow when it is hot enough) or molten glass mixed with something else.
Realtalk- that is a racist comment. It is not far fetched to have a wealthy "cave man" finance the attacks, and send hijackers to US flight schools.
