Yes Would definitely have been Air UK you flew with, they operated STN-GCI until their demise in 1998.Shorts 360 flights from Stansted were very short lived, about 1 year I think 1986-87, most flights were on the F27 Before that and then a mix of F27 and BAE 146,possibly F100 towards the end[weekends] from 1988 onwards.
They also downgraded the SOU route from F27 to SH6 at that time too.
Not sure what the reason was but it was very short lived and was back to the F27 within a year or so. You definitely got some bumpy landings into Guernsey when it was windy on the Shorts!
