We had no idea that day that 9/11 was not a normal, clear blue day for aviation. On the contrary, it was one of the busiest days in the history of American aviation, a dense forest of live flying exercises, simulations, fake radar injections and total confusion. And that was even before the attacks started! This is the story of 9/11 that you did not see on your TV on that fateful day in 2001. This is the story of the 9/11 War Games.
