One of those crews was ABC13 reporter Tom Abrahams and former photojournalist Jaime Zamora.
They drove for 25 straight hours to Washington, D.C. to visit the Pentagon. It was still smoldering when they arrived.
On Friday, Abrahams recalls every moment from that day. He was a young father at the time and shares his memories in detail in the video above.
This 9/11 comes a little more than two weeks after a suicide bomber in Kabul killed 13 U.S. service members as the military concluded its withdrawal from Afghanistan.
