My all time favourite has got to be
Fair Isle in the Shetlands.
I have only been there once, as a pasenger, but I managed to grab the front right hand seat, in the Islander, as no one else wanted to be up front with the pilot.
The runway is 486m x 22m of GRAVEL!
Per
Pooleys:- Runway is banked above surrounding land & is subject to turbulance with Westerly winds. Ground falls away very steeply approx 30m from each runway end. Runway surface prone to moss growth & may be slippery in patches, particularly when wet.
I was the most thrilling landing that I have have sat through, I was very glad that the pilot was a skilful, ex Royal Navy carrier pilot.
And during the walk from the Fair Isle "Airport" the Arctic Skuas dive bomb all the passengers.
