Thanks for the memory & info Keanaga...
As stated the service was commenced by Norsk Air to Stansted with it`s then newly opened terminal..
The service ceased with or before Norsk Air`s financial problems in the late eighties/early nineties.
Norsk Air was subsumed into Wideroe who restarted the flight using the Fk50 of Busy Bee as you say,(I remember the Fk50 but wasn`t aware it was basically a Wideroe service).
I also remember the Busy Bee B732 out of the old terminal North side but that was part the Scandi Sunday influx back in the day.
Records state the destination was Sandjeford in both instances & not Kristiansand KRS as planned now for 2018.
