This was how the military reacted after terrorists attacked on Sept. 11

On the day that 19 terrorists from the radical Islamic group al-Qaeda attacked the United States using airliners as cruise missiles, the U.S. military jumped to respond.

And it was a response that began even before the Pentagon was hit.

Some stories of 9/11 are well-known, including then-Secretary of Defense Donald Rumsfeld racing to the scene of devastation at the Pentagon to aid victims of the attack, or the pilots plan to ram Flight 93 foiled hadn’t by passengers on the plane.

But there were other heroic deeds during the attack.

According to the 9/11 Commission report, when word reached North American Aerospace Command, also known as NORAD, of the first hijacking, two F-15 Eagles from the Massachusetts Air National Guard were scrambled to try to intercept the planes. They took off just as Flight 11 hit the North Tower – WTC 1 – at 8:53 AM on that Tuesday morning.

NORAD had last dealt with a hijacking in 1993. One thing that worked against NORAD during that terrible day was the fact that that there were very few sites from which interceptors could launch.

During the Cold War, the 9/11 Commission Report noted, there had been 26 sites.

Other military jets — F-15s from the 1st Fighter Wing at Langley Air Force Base in Hampton Virginia, and F-16s from the District of Colombia Air National Guard based at Andrews Air Force Base — had also scrambled. Pilots from the latter unit were armed only with dummy rounds for their M61 Vulcan 20mm cannon.

The F-15 pilots, according to the commission report, didn’t even know they were looking for hijacked airliners. The lead pilot would later be quoted in the report as saying, “I reverted to the Russian threat. …I’m thinking cruise missile threat from the sea.”

It as a credit to NORAD, that even though they were unable to keep the airliners from hitting targets, military personnel were able to face an unprecedented threat and challenge with an improvised air-defense system cobbled together in a matter of hours, despite having never trained to face that threat.

On the first day of what one unidentified officer called “a new type of war,” they reacted with skill and professionalism.
