In 1968 Martinair bought two DC-8-55Fs from Overseas National Airways. Transatlantic leisure charter flights had begun in 1967 and PH-MAS is pictured on one of those from Amsterdam. Also used for freight charters, the aircraft was sold back to McDonnell Douglas in January 1977. Leased to KLM for the summer, it was sold to Aviaco as EC-DBE in October 1977.
