Trump calls for cancellation of Air Force One replacement order with Boeing

A tweet from president-elect Donald Trump calling on the U.S. government to scrap an order with Boeing Co. for the development of a replacement for the Air Force One jet temporarily knocked about $1 billion US off the stock market value of the aircraft maker. "Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than $4 billion. Cancel order!" Trump tweeted Tuesday morning.
