Will Air Force One be Upgraded?

According to New York Times President-elect Donald Trump post a tweet saying that he wants to cancel the order of a new Air Force One. Trump claims that the plane would cost too much and he could still continue to use is own 757. The Secret Service and the Department of Defense claims that Trump's decision is a bad not because of the convenience will be lost but because an array of top-secret communications gear will be lost as well. Trump has bought some of Boeing's stock and on his campaign said that he wants them to make money but not that much. The new Air Force One would be the new Boeing 747-8 which will have new technological advances and a longer range. The new plane would cost over $4 billion and it the decision that Trump makes won't affect him. The new plane is scheduled to be delivered in 2023 but Boeing is known to have a back up in schedules. If Trump were to be elected a second term at most he would only enjoy the plane for a year at most.
