New 9/11 Conspiracy?

During a Christmas Eve speech to U.S. troops in Baghdad, Secretary of Defense Donald Rumsfeld made a passing reference to United Airlines Flight 93 having been shot down. Flight 93 went down with no survivors over Shanksville, PA, while other hijacked flights that day struck the Pentagon and New York's World Trade Center. The official story is that the hijackers intentionally crashed Flight 93 because they feared the passengers would overwhelm them.
