Michael McCormick was the FAA air traffic manager at New York’s Air Route Traffic Control Center on September 11, 2001, overseeing the airspace across the Northeast as the attacks unfolded. He watched the hijacked planes’ movements in real time, recognized that the country was under attack, and played a key role in the unprecedented decision to shut down the nation’s airspace. McCormick joined Dan to reflect on the chaos of that morning and discuss how 9/11 changed aviation forever.
