Is there a Structural Engineer who can explain Expension, Gravity Anchors, Hanging Steel Construction Techniques, Slippage, Explosive Decompression etc to a lay person?

Well, it appears that you are looking for a "conspiratorist" to answer your question and tell you that it "is all the government's doing. That Bush wanted to create a war".
Sorry, the buildings collapsed because the airliner collided with the buildings. The collision and the flames combined to weaken the structure enough to allow the buildings to collapse.

Those answers have been given, albeit by speculation. Since there were no measuring devices in place at the time of the collapse of the towers, only the design specifications, knowledge of the materials used and the way in which the building was built can actually be used to give any kind of reasonable answer as to why the buildings fell. One section became hot enough that the metal could no longer sustain the weight of the structure above it. When those beams buckled, the rate of fall accelerated, and the rest we all know.

In fact, the twin towers are designed to withstand the crash from a Boeing 707. But not with filled tank. 767 is a wide-body jet, the bigger payloads it carries result in much more fuel. The tremendous amount of energy the fuel carried caused the failure of part of the structure. The impulse created by the building above the failed section crushed the entire building. This is fact.

I don't know why the building "collapes" as stated in your question; however the building "collapsed" because a big air plane flew into the side of it. Where have you been the last 5 1/2 years?

well as far as my knowledge goes..when the plane with tank full of fuel hit the building friction was developed and as a result fire broke out..and the heat generated was so high that the steel in concrete of building melted, as a result the building collapsed.
