Boeing (officially named The Boeing Company) is one of the world's two largest aerospace manufacturers and also the largest US exporter. The company was founded in 1916 and since then operates worldwide with its headquarters in Chicago, Illinois. In 1997, Boeing was merged with McDonnell Douglas, an American aircraft manufacturer. With revenues of around $ 30 billion for arms sales, this multinational corporation is also third in the world of arms suppliers. They still compete with the European Airbus. The difference between Boeing and Airbus is primarily in the view of the pilot-computer relationship.
