Sud Aviation Caravelle
While competitors first looked at turboprop airplanes to replace their piston-engined craft, Swissair introduced jet airplanes. Together with SAS, Swissair bought Douglas DC-8s, which were delivered beginning in 1960. For medium- and short-range routes the Sud Aviation Caravelle was purchased. The aircraft were maintained in concert with SAS, and manuals for operation and maintenance were co-written.
