I remembered today when I watching 9/11 attacks live on BBC there were reports that a 5th plane was being moved into USA air space. 2 planes crashed into the world trade center. 1 plane crashed into the pentagon. 1 plane crashed in the farms far away. All the USA airports were shut down and all the planes were grounded. The BBC report about the 5th plane appeared some 1 or 2 hours (not sure) after the first plane crashed into the World trade center. What happened to the 5th plane? Any information regarding this.
