Lets see exclusive's points.
- weakened metal, metal on fire - addressed. Only has to be weakened enough to stress other members.
- factor of safety - addressed. WTC had a lower than normal factor of safety du to the need to keep the structure as light as possible. Add to that the large chunks missing because of the crash.
- panckae theory - addressed. Dynamic loading and excessive forces on consecutive adjacent members. The debris that fell in the time expected for freefall was just that, debris. With all the dust, It would be extremely difficult to see how long it took the floors to fall.
- aluminum in the pentagon. - Ok, not huge amount of explanation possible without access to the site but it is feasible that melted aluminum was mixed with all the other debris. This is the only point that was sidestepped for lack of evidence. overall, science looks for evidence, not conjecture and there is more than enough evidence to deal with all the other theories.
From a political slant, what reason would the us blow up or cover up a bomb or rocket attack, especially on such short notice?
