Refueling Can Happen Mid-Air
AF1 has a unique feature. It can refuel itself…and it can do it in the air. A reserve tank can replenish the main fuel tank even when the airplane is zooming through the air at an attitude of 35,000 feet.
Because it can refuel itself without stopping, the plane can fly anywhere in the world and get to its far-off destinations without having to stop for gas.
