Being generous to the government-backed fire-collapse theory - just before a random event occurs the rate of occurrence will tend below the mean; after the event it will tend above the mean. Let's suppose 3 collapses in every 100 years is the average fire-induced collapse rate to be expected for steel framed high-rise buildings in the US (and the fact that the rate remained at zero for so long suggests that this is an overestimate). So the rate is one day every 33.333 years = 1 day every 12,175 days. Hence, the probability for one such collapse to occur on any specified day is 1 in 12,175, and the probability for three collapses is 1 in 12,175 cubed = 1 in 1.805 trillion.

Well that is a shame...cause the same people who build these types of buildings...such as myself....A structural Engineer....do Have a wee bit of understanding....unlike yourself i guess.
But it is not fair of me to assume that cause i don't know you...But you assume What???? ...cause your a truther you dont have degrees...or understanding...

Not at all. My responses are for those who state that there is no way the buildings could have come down due to fire and structural damage. This is simply not true. As an engineer, you know several things about building, especially high rises.
1. An engineers plan is almost never followed exactly.
2. Due to time constraints, work arounds are unfortunately common thus allowing the buildings to be finished faster even though structurally, they will suffer.
3. You understand that once a structure is damaged, the remaining structural components must carry the load. At some point those overloaded components WILL fail and there will be a global structural collapse.
So for someone to say that a failure of this type is simply not possible, it tells me they don't have knowledge of how these or any buildings are actually built.

What are you saying? is the above [a trying to be real] statement from a builder, if it is,you then have admitted that first off, the 9/11 commission don't know how they were actually constructed,(there is some evidence for that) and that the NIST along with their cartoons don't know how they were actually constructed. That leaves everything back to square one does it not? Load transference on the other hand would be an engineers forte and not something to be monkeyed with, it's not Fawlty Towers we are talking about, or is it?

Is it possible yes...anything is possible. Is it logical for three steel structures of their magnitude to crumble because of fire? As stated earlier, this is the first time in US history that steel structures such as those have succumbed to falling do to fire.

There were some pictures of the Floor Space before 9/11 showing some of the Welds on the Floor Trusses had
cracked. There was also evidence the Trusses when made were not checked for flaws with XRays. Not all were
XRayed, some were Faked to save money. There was a similar story with some of the Concrete being sub-standard.
With a Building that size, corruption and inferior quality has to be everywhere.
