@Robert Gentel,
OBL didn't fail. He is living large somewhere funded by the US government.
The science that has been put together by thousands of science professionals around the world has proven conclusively that the USGOCT is a total lie, beginning to end.
There were no Arab hijackers, [they can't melt/vaporized WTC structural steel - this seems to escape so many of you, why?], which means that OBL had absolutely nothing to do with the US government planned and carried out attack on WTC, Pentagon, ... .
