Wrong again. They weren't pilots, they were engineers and building designers.
Hey, a 757 or 767 cannot fly at 600mph so close to the ground without coming apart,
but engineers ALWAYS over build the applications by at least a factor of 1.5 times what is going to be required, and more typically they design and build over by a factor of 3 times what is going to be required.
With regards to the 1 & 2 WTC, the outside columns, from bottom to top, were able to hold up to 5 times the weight above them. The inside, or core columns, were able to hold 3 times the weight above them. Why? They over built for the applications.
Now, you may be a pilot, but you are definitely not a an engineer.
