That was from flightradar24. There are some anomalies in the way that flightradar24 records flights but looking at the detail there is definitely a record of 3 short flights that are 13 to 16 minutes long and are circuitous around local fjord and nearby islands. The first is 1129h 26th, second 0643h 27th, third 1224h 27th. The first has a routine flight number and so may be a RTB after normal departure. No other flights are shown during that 25 hour period.
