Flight 93 (if it was the original plane or replaced with another because on the outside of the plane there was 2 missiles attached to the belly) was shoot-down by US Air Force (see HAPPY HOOLIGAN plane).  The pilot was awarded with a medale next year (2002). He is a hero. Without him, the White House had been destroyed and the martial low instaured in USA. 911 was a INSIDE JOB.
