Panama City- On Tuesday, Tyndall Air Force Base officials reflected back on the attacks of September 11th.
The ceremony marked the exact moment that the first tower went down on that fateful day in 2001.
The base has a September 11th memorial built of actual steel beams from one of the World Trade Center towers, plus, limestone from the face of the Pentagon.
Leaders from the Continental U.S. North American Aerospace Defense Command Region, and the 601st Air and Space Operations Center say the attacks caused major changes in the military's day-to-day operations.
"When the events of that day started unfolding, the FAA and other agencies understood there was a problem and understood the magnitude of the problem long before the Department of Defense got involved. That was because of a lack of communication. The rolodex didn't even have some of the phone numbers to give us a call," said Colonel Randy Spear, the Commander of the 601st Air and Space Operations Center.
Officials in the AOC say they now work closely with organizations such as the FAA for better air monitoring.
