Did the Barra flight with my Dad last year.
Going Stanby, we had to wait to see if it was us that got on or a bag mail and Newspapers!
The view as you go out is amazing, and the landing was interesting too! If you get a chance to do it the do. Even more interesting is that the whole island seems to appear around the airport as it comes in to land, then go away again once it's parked.
Same day, also saw someone get their plane stuck in the sand as he taxied to take off
