FOX45 News sent a crew to cover the attack on the Pentagon on 9-11-2001. This story originally aired that day.
"But I am truly terrified," said one Pentagon worker.
The pillar of national security brought to its knees along with our nation's sense of security.
"I heard a big 'boom' sound. Plastic from ceiling falling on me. Seeing people running - smoke in the hall," said one Pentagon worker.
"Caused us all to go into a battle mode - fall down on the ground, cover yourself," said one Pentagon worker.
All 23,000 Pentagon workers evacuated just before 10:00 this morning after a hijacked commercial airliner slices into the southwest end of the building - crumbling walls, sending people scrambling.
"We're scared. A little shaky. A lot shaky," said one witness.
"I just heard a big huge explosion and, you know, shaking of structure," said one Pentagon worker.
Ambulance after ambulance brought in to help the injured helped by air and water too. So much chaos, even cars, carted out the hurt.
"It's something we prepare for, but you're never ready for it even though you prepare for it," said one witness.
The extreme heat and flames keep search and rescue crews at bay until late afternoon when they are finally able to enter the Pentagon and search for survivors.
"Here in Washington, D.C. we are at threat condition Delta. That is the highest condition that we can go to," said one military official.
The nation's military, on highest alert, just like people's fears.
"Some of my friends could be still in there. Some of my co-workers could be hurt. I pray for them all," said one Pentagon worker.
Luckily, for Doug Neville, his four-year-old daughter and nephew were right where he left them this morning - in the Pentagon daycare center.
"My first instinct was, of course, get out of the building. I can see the plumes of smoke and then I walked around the perimeter of the Pentagon to get to the daycare center. And of course, all the kids are fine," said Neville.
