The events of 9/11 as they unfolded through actual audio.
Angel Flight (Radio Tower Remix)
By LtThompsonCS on YouTube: "If you did not figure out via pictures already, Angel Flights are the U.S. Air Force planes (C-130's) used to fly home our Fallen Soldiers. Angel Flight is also their call sign. In addition, Angel Flights have top priority in U.S. Airspace - as you saw the Towers say "number 1 for landing/takeoff" .... now of course, I know, there are other flights that have an even higher priority ... but in reference to other standard military flights, Angel Flights get number 1 priority."
