Remember we said that Air Force One could deal with a fuel load of 53,000 gallons? That's a huge amount - far more than you'll find on a commercial airliner. With all that fuel, you get a lot of range.
If Air Force One takes off from Washington with a full tank of fuel, it can make it all the way to Tokyo in Japan without having to stop off for refueling on the way. That's a massive 6,700 miles through the air.
