President-elect Donald Trump is not happy with finding out how much the next Air Force One aircrafts cost. He's been vocal about renegotiating the deal with Boeing for the next generation of "flying White Houses" but it is for this very reason why the plane is ridiculously expensive.

The plane is supposed to provide the president services available in the White House.

The current Air Force One was acquired back in 1987. The 2 new planes being commissioned for an estimated $3-4 billion will be ready by 2024.

According to Vox, 'Air Force One' started as a call sign when presidential flight had the same aviation call sign to a commercial carrier. Technically from then on, any Air Force aircraft that carried the president became Air Force One. Any plane in the US military for that matter.

The plane became the symbol of America's military might, CNBC reports that for every hour of its flight, President Obama's Air Force One costs $206,337, according to a Freedom of Information Act letter obtained by the nonprofit Judicial Watch.

Air Force One is a custom Boeing 747-200 that has 3 levels and 4,000 sq. ft. of interior space that includes a conference room, offices for senior staff, a medical operating room, press area, 2 food preparation galleys and the president's private quarters that has a mini gym, lavatory, shower and sleeping quarters.
