It was operating for Austrian Airlines but it would seem (looking at Alastair T. Gardiner's photo taken 2 days previously) that the Austrian titles were only on the port side of the aircraft (i.e. the passenger entry side).
Aero Jet was founded in 1992, a year after the demise of City Air (a previous Swiss airline which also used this Caravelle in this livery). Aero Jet ceased operations in early 1996. The text on the nose is not a name but simply says "Super 10", referring to the aircraft type.
