At any given moment, roughly 5,000 planes are in the skies above the United States. In one year, controllers handle an average of 64 million takeoffs and landings. For every one flight you see listed on an airport monitor, two you don't see show up on air traffic controllers' screens.
In 2001, the average plane was 22 years old. The Air Force says it wants to buy new planes to lower the average age of its fleet to 15 years over the next two decades. That will cost an estimated $400billion. There are 356 A-10s in service.
