Why do you have to make up lies about 911? Videos/Movies show 11 and 175 impact the WTC, these are backed with RADAR, to the second. It is hard evidence you ignore, that make your claims nonsense.Think of it as a relatively simple 'David Copperfield' trick, with planted objects to fool the 'audience' and planted actors pretending to be witnesses, such as: http://www.youtube.com/watch?v=zMelmLspMP0 who incredibly survived by taking cover under a desk (?!).
Why can't you comprehend RADAR data?
