The call came in to the Arlington County Fire Department at 11:16am on July 2, 1959… The Pentagon was on fire.
ACFD units raced to the scene, soon to be joined by deployments from 34 other jurisdictions including Falls Church, Alexandria, Fort Myer, the District, Prince Georges County, Bethesda and the Inter-Agency Government Pool — over 300 firefighters in all.
When trucks reached the scene, black smoke hung over the building, so thick that they had to form a human chain in order to navigate. Firemen groped, clawed and cut their way to the blaze, which had erupted in the Air Force statistical services offices between rings C and D and corridors 1 and 10.
