The Germans destroyed the fleet in April 1941. The company continued to operate after World War II and flew DC-3 Dakota aircraft until 1951 when the Greek government ordered the merger of the three existing companies into a state-owned company called Technical Air Operations—National Air Letters. This airline operated without competition on national routes and offered a small number of destinations to cities in Europe and the Middle East. The airline was sold to Aristotle Onassis in 1957 and he renamed it Olympic Airways
