yes, but all these building are not the same size as WTC 1 and 2. Also the building itself is not designed in that way with exterior walls, it's floors are held to the frame of the building with several rivets, the core of the tower is the actual strongest part. You need to watch the numerous engineering documentaries on this.

Added to that, depending on where the planes hit, it also had about 20 to 50 floors above it. So with basic physics, it's like a jenga tower.

Even if you look at the most recent India air crash last month, the building still stood quite firm. The height + gravity is what made it collapse that way.

BTW there's nothing crazy about these guys flying planes into buildings. Throughout the 90's they realised they could and have done it. I think 9/11 was greater than it would have been, given that the towers did end up falling completely, and what made it more visceral was that by the time it came down, almost everyone was watching.
