Barra, one of the southernmost of the Outer Hebrides of Scotland, has an unusual airport. The landing strip is the beach, so flights can only come and go at low tide. It is the only beach runway in the world which handles scheduled airline traffic. We were lucky enough to catch some spectacular light when this Twin Otter was taking off. I suspect the runway is also the only one in the world where dogs catch frizbees and people fly kites and dig for cockles between flights.
