How many times does Yahoo censure truth?

I am so surprised that your question was not deleted. You have a lot of great information here. There are things about 9/11 that will never be right in my mind. The biggest one is why was the hole so small in the Pentagon...when the plane of that size should have tore a monster whole? Why were the top execs out of the Pentagon on 9/11....while their normal attendance was astounding?
