Merger of Boeing and McDonnell Douglas At the end of 1996, Boeing and McDonnell Douglas, the world's two largest aviation manufacturing giants, announced their merger plans. After the merger, Boeing will monopolize more than 65% of the global aircraft market. This large transaction involving a transaction volume of US $13 billion made Europeans very panic, because the European Airbus company was already at a disadvantage in the competition with Boeing, and the merged Boeing would be stronger, and Airbus would undoubtedly suffer more.

Thus the unprecedented "Big Mac" in the air was born.
