Homegrove it could be an aircraft repositioning flight i.e. to park it in its hangar, garage or next pick-up point etc.
Also, to be extra dull, when I put it in to google it states “typically 30-45 minutes” between the 2 airports on Saturday at 10am, which is when the flight was; plus there are people in the comments section who say it was more like 1 hour at the time.
