#3: Mid-Air Refueling
Contrary to popular belief and akin to the cinematic depiction in Air Force One, the presidential aircraft is equipped for mid-air refueling. This complex emergency protocol ensures the plane can refuel without landing, a marvelous capability for urgent situations.

Mid-air refueling is a marvel of aviation technology, involving an extended pole from the aircraft, serving as a conduit for fuel from another flying tanker. This allows the plane to receive fuel and continue its journey without touching down.
