While competitors first looked at turboprop aeroplanes to replace their piston-engined craft, Swissair introduced jet aeroplanes. 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.
