On the left side is the east end of Concourse D (formerly A) which is where the former Eastern Airlines Air Cargo building was from the 1960's to 1990's. The former National Airlines headquarters and maintenance base extends eastward (to the right) from the large hangar, formerly brown and tan and now "Ghastly Grey", and corporate headquarters of National Airlines. National was bought by Pan Am in 1980 and the National buildings were used by Pan Am until they died on December 4, 1991. American Airlines leased the hangar, and a few floors of the corporate offices after Pan Am died. Also visible in the photo are the elevated MIA Mover tracks and the airport's Central Boulevard being rebuilt to put a bridge over Perimeter Road instead of Perimeter Road's old low bridge over Central Boulevard which has been removed.
