Pentagon Memorial honors the fallen

A flag marks the entrance to the Pentagon Memorial that honors the fallen of 9/11.

Arlington Fire Department volunteer Bill Kehoe, who stood fire watch on the Pentagon roof 9/11, stands before the locator stone with the victims’ names and birth years.

A marker at the gateway of the Pentagon Memorial captures the precise time Flight 77 hit the Pentagon on 9/11.

Each Memorial Unit in the Pentagon Memorial features a bench engraved with the name of one of the 184 fallen and a small reflecting pool.
