Over a million dollars' worth of diamonds and bonds were apparently stolen from an armored truck in the basement of the World Trade Center when the terrorist attacks took place on September 11, 2001, which suggests that someone--or some people--may have had foreknowledge of the 9/11 attacks and exploited the chaos they knew the attacks would generate in order to commit their crime at a time when there was minimal risk of getting caught.
Furthermore, there was an attempt to remove an unusually large amount of gold from vaults in the basement of the World Trade Center at the time of the attacks, which indicates that other people may have known in advance about the attacks and, based on their foreknowledge, tried to get the gold out before it became buried in the rubble of the Twin Towers. Whoever was transporting the gold away from the vaults apparently abandoned their vehicle and escaped to safety before the towers collapsed, which suggests they were warned in advance about the collapses and were consequently able to get away before the buildings came down.
Only a limited amount of information has been reported about these incidents, which are described below, and so it is difficult to determine exactly what happened. However, the details that have been reported certainly seem suspicious and so there is surely a need to look into these events closely.
