Straits Air Freight Express (SAFE) was a cargo airline, established in 1950, named for its Cook Strait focus and connecting the North Island and South Islands of New Zealand's railway systems from the 1950s to the 1970s. The company was renamed Safe Air Limited in 1966 and diversified into aviation maintenance. In 1972 it was bought by the National Airways Corporation, which then merged with Air New Zealand. Safe Air continued to be operated as an independent entity by both owners. It ceased flying in 1990, but has continued to expand as a maintenance facility and now employs approximately 350 staff. In 2015 it was bought by the Australian arm of Airbus.

The Armstrong Whitworth Argosy was a British post-war transport/cargo aircraft; it was the final aircraft to be designed and produced by aviation company Armstrong Whitworth Aircraft. Although given different internal design numbers, the AW.650 civil and AW.660 military models were, for most practical purposes, the same design, while both models also shared the "Argosy" name.
