Air Force One is a special case, while you may think it’s the name of a military base, it is in fact the name of a plane! To be more specific it’s the President’s plane. The President has to be able to fly at any time so of course he is going to have his own private plane. It is very important that no one tampers with this plane, so it is on lock down at all times except to those maintaining it. With cargo as precious as the president, people have to be extra careful so that everything runs smoothly.
The plane also has many interesting features, it is able to refuel in the air, has defenses against EMPs and can even function as a Base of Operations if necessary. Additionally, it has plenty of places to prepare food and an operating room with a full time doctor. It sure is the supreme mode of travel to go to just about any golf course in the world!
