Osama bin Laden's driver knew the target of the fourth hijacked jetliner in the September 11 attacks, a prosecutor said. Prosecutor Timothy Stone, in an attempt to draw a link between [Salim] Hamdan and the al Qaeda leadership in the first Guantanamo war crimes trial, told the six-member jury of U.S. military officers ... that Hamdan had inside knowledge of the 2001 attacks on the United States because he overheard a conversation between bin Laden and his deputy, Ayman al-Zawahiri. If they hadn't shot down the fourth plane it would've hit the dome," Stone, a Navy officer, said in his opening remarks. "Virtually no one knew the intended target, but the accused knew," Stone said. United Airlines Flight 93 crashed in a field in rural Pennsylvania. U.S. officials have never stated it was shot down although rumours saying that abound to this day.
