As Quizmonster says this is what Brits would usually be referring to. As an aside, it was called Special Air Service to confuse enemy intelligence (unit formed during WWII) as the SAS has precious little to do with flying.
In face, rekstout, the Special Air Service was originally planned to parachute behind enemy lines to do their dirty work, but the first operational parachute drop was a disaster because of a strong wind. So they changed to going in at ground level, originally with modified armed jeeps. Today they probably have the expertise to go in any way they choose.
The airline is Scandinavian Airlines System, based in Copenhagen, Denmark. It is the national airline of Denmark, Norway and Sweden.
Finland is not considered as a Scandinavian country but a Nordic one and has its own national airline, Finnair.
