Caught part of a program last evening, "Inside The Pentagon, 9/11/2001.
Had never heard this before, but when the plane hit, it damaged the water systems, rendering the firefighters with little to no water pressure with which to fight the fires.
The Building Manager and a group of on-duty civilian maintenance workers , plumbers, electricians, etc. were inside the building, trying to repair that when word of another plane approaching was announced and everyone was ordered to evacuate to a distance of five-hundred feet. Those workers refused to abandon the task they were undertaking.
The plane turned out to be a U.S. Fighter Jet.
But, still, everyone thought a second airliner was coming just as a second plane had come to The World Trade Center.
And, I don't know if they still do it, but for years The National Geographic Channel has replayed the news reports and videos as they occurred on 9/11/2001.
