You are so RIGHT! Sheen has been on drugs so long that any brains he had are gone; as far as being his "not being man enough"...I would say that Charlie Sheen is not a "man" at all!
Sheen is a loon but I don't think it's a stretch to think the terrorist didn't have a Backup Plan that had some of the buildings rigged with explosives if they weren't able to crash the planes.
