Data from ATDB.aero shows that United Airlines operated a total of 59 DC-10s over the years. Of these, 48 were examples of the original DC-10-10 variant. This version first flew over 51 years ago, in August 1970. It entered service a year later, and McDonnell Douglas produced 122 in total. This means that United alone flew around 40% of the total output. (simpleflying.com) 更多...
