Lizzie...."WHY are all the experts coming out demanding questions are answered? "

They're not. SOME folks who take rhetorical questions as serious discussion are demanding 'answers', whether there IS an answer that fits their theories or not.

"Why did so much evidence 'disappear'?"

It didn't. There are claims about 'evidence' that never existed.

Look at the images in this page and read the witness reports! They thoroughly refute ONE theory... other pages deal with other theories, yet you rely on 'heroes' theories because....ummmm... because they're nice guys?
In past threads, we have posted explanations of what really happened to Larry Silverstein's buildings..... yet you just continue to go back to the assertions that show what you have now committed to.

In short, there are many, many experts and their detailed explanations on the web which make FAR more sense than just guess work by armchair conspiracy nuts. You simply have chosen a set of 'questions' that you claim are not answered...and which cannot BE answered because it is a circular argument to assert that because they are not answered, they must be true!

It has been EXPLAINED why buildings fell as they did... yet you look briefly at the technical explanations, and again assert "...but buildings CAN'T fall that way! I know because several people said so!"

I suppose that, 100 years from now, after no 'hidden conspiracies' are revealed, someone will say the same things again....
