The Douglas DC-4 originated from the unrelated first DC-4 (which was renamed the DC-4E) that had proved too complicated and lacking in performance prior to World War Two. The advent of the war interrupted the new DC-4s use as a commercial airliner and after the first prototype was constructed nearly 1,170 came off the production lines for the military in a large number of variants. The basic types were named the C-54 Skymaster (for the USAAF) and the R5D (for the US Navy).
The Fokker 100 (or F28-0100) was, Dutch manufacturer, Fokker's next generation of its popular and steady, if not spectacular, selling F28 series. The F28 was a fine aircraft well ahead of its time pre-dating true regional jets by nearly thirty years. The type was operated worldwide (especially in Australia, Canada and Europe) but usually in only small numbers. Its maximum seating capacity in the extended 4000 series was 85 and by the 1980s the basic design was in need of renewal. Fokker accomplished this by creating a new wing, replacing the Rolls-Royce Spey engines with new Tays and stretching the fuselage to seat up to 107 passengers.
In the early 1980s American ordered the first of what was to be 280 MD-80s (nicknamed Super 80s in service but informally known as Mad Dogs) to begin replacing its 727 fleet, with the first (N203AA) arriving in May 1983. Deliveries ran until August 1992 and no other type defined American so much throughout the 80s and 90s.
