Royston, the term "conspiracy theory" has no place in a logical and rational discussion of this subject. It is an ad hominem argument that is designed for only one purpose - to smear those to whom it is applied, and thereby silence them. It is not a rational argument or counter argument. I can understand that you need to believe the official version, even with no evidence to back it up, because it's traumatic to think that the US government could possibly be responsible for something as tragic and disturbing as what happened on 9/11. This is a very understandable impulse. But it's not science.

So give me the scientific explanation of how it was possible for the towers to fall.
