(The official story of 9/11 gives 9:37 a.m. as the time the "plane hit the pentagon," but many clocks stopped at 9:31 and 9:32, and witnesses inside the building say there was an explosion at that time):

Converging Lines of Proof of a 9:32 Violent Event at the Pentagon on September 11, well before the Official Story says anything hit the building:

Multiple standard-issue, battery-operated wall clocks on the walls of the area of the Pentagon attacked on 9/11 -including one in the heliport just outside the west face- were stopped between 9:31 and 9:32h2;1/2 by a violent event, almost certainly a bomb or bombs inside the building and/or in a truck or construction trailer parked right outside the west face. The first Associated Press report, in fact, stated that the Pentagon had been damaged by a "booby trapped truck." The Navy posted the stopped heliport clock on an official website and another of the stopped clocks is in the 9/11 display at the Smithsonian Institution.[2] These are just some of the west section Pentagon clocks that stopped between 9:31 and 9:32h2;1/2 on September 11.
