McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft of James Smith McDonnell and the Douglas Aircraft Company of Donald Wills Douglas in 1967.
The corporation was based at Lambert-St. Louis International Airport near St. Louis, Missouri. Between then and its own merger with Boeing in 1997, it produced a number of well-known commercial and military aircraft such as the DC-10 airliner and F-15 Eagle air-superiority fighter.
