Today, there are actually two planes that regularly fly under this designation -- nearly identical Boeing 747-200B jets. The planes themselves are designated VC-25A, with tail numbers 28000 and 29000.
The top speed is between 630 and 700 miles per hour and the ceiling maximum (how high the plane can fly) is 45,100 feet.
Each plane carries 53,611 gallons of fuel and weighs 833,000 pounds fully loaded for a long-range mission.
With a full tank, the plane can fly half way around the world.
