I don't mean to attack a newcomer but didn't you say you believed in the scientific method? This requires research; more than just expecting everyone else to answer your questions. Jon has given you many links to follow. All these links are well sourced. When I first started questioning 9-11 I had questions too and still do,(you can see by my first post) and if someone provids me links to read and gather data or books etc. I would read them.

I cannot take someones endeavors for clarification seriously if they choose not to at least try. You watched Press for Truth and thats a start, but as Jon said it doesn't even scratch the surface of incosistencies and implications that exist.
