DC-6B from Sterling Airways Denmark.
Sterling Airlines traces its history back to 1962, when Eilif Krogager, founder of Danish travel agency Tjæreborg (today part of MyTravel Group), started the charter airline Sterling Airways with two Douglas DC-6B bought from Swissair, in order to better service his own package tours from Scandinavia to the Mediterranean. Further DC-6Bs were acquired in 1963. In 1965 Sterling received its first Caravelle, and in 1968 the company was bought out of the Tjæreborg Group and started servicing other travel agents as well.
In 1987, the company celebrated its 25th anniversary with 19 aircraft and almost 1,300 staff, but a few years later, in 1993, Sterling Airways went bankrupt. In 1994, the estate after Sterling Airways re-created the company as Sterling European Airlines, with three aircraft and 182 staff.
On 29 October 2008, Sterling filed for bankruptcy and ceased operations. On 4 December 2008, Cimber Air announced that it had purchased Sterling and intended to restore the airline as a separate company, with a gradual expansion throughout Europe. The purchase included Sterling's name, website and landing slots, but not aircraft.
