I guess you could say the first MD
Series aircraft was the MD
-80. Then the revampted DC-10, the MD
-11.... then MD
-90 and MD
-95 which later became the 717.
So, to answer your question... there is no longer a production of a 'true' MD
aircraft. The Boeing 717 (MD-95) is still in production, but I thought I read that would come to an end as Boeing already had aircraft that fit that market.
