Air traffic controllers receiving reports about hijacked planes 30 minutes before the first plane struck the World Trade Center were one of the first groups of people who realized what was happening on 9/11.
Today the FAA released a short video that shares the perspective of three air traffic controllers who worked that day. It's a sobering account of the events of that morning and the scramble to clear the air space. "Okay, we gotta put these aircraft on the ground," said one controller who was interviewed. "So we were working with the controllers to then tell the pilots 'you're going to have to land...you're going to have to pick an airport...tell us where you're gonna land."
