Air Force One

The Air Force One was an aircraft used for President of the United States and the other politicians.

Overview
Air Force One is the official air traffic control call sign of a United States Air Force aircraft carrying the President of the United States. In common parlance, the term refers to those Air Force aircrafts specifically designed, built, and used for the purpose of transporting the president. This aircraft is a prominent symbol of the American presidency and the power it holds. In the Highschool of the Dead universe, "they" somehow manage to get inside Air Force One midflight, infecting the First Lady, the President, and other government officials. Having taken refuge in a cabin, the President's chairman insists that the ICBMs must be launched in fear that other countries will launch theirs at the US. After some hesitation, the president accepts as a flight attend shoots the chairman who is about to turn. The scene then switches to the airplane flying above a burning Washington DC. The wreckage of Air Force One is later shown in Episode 11, assuming that all members inside died.

It is also heavily implied that the President was previously the Secretary for Homeland Security, and that the original Commander in Chief died from the disease. This can be heard in a dialogue between US Navy members.
