so you started a new post instead of defending you original lie.

let me point out that phd whats his name is comparing the wrong model boeing 707 against the boeing 767. the model that the wtc was designed to withstand a hit from was the 707-020. the first boeing 707 model. the 707-020 weighed 222,000 lbs full and 103,145 lbs empty. the design of the wtc started in 1958 and was completed in early 1963. the boeing phd whats his name is using as the basis of his incorrect comparison is the 707-320B which didn't start production untill late 1963 early 1964. so the weights used are dead wrong. the statement that the wtc was in essence designed a hit from a 767 is dead wrong.

further phd whats his name uses a lot of estimated speeds that do not stand up to reality. both planes were speed up prior to impact by the al qaeda pilots inorder to maximize the kinetic energy transfer. so the kinetic energy was much greater than phd whats his name indicates.

perhaps astaneh-asl is just another muslim that can not confront the true evil of muhammed's teachings and the evil of islam.
