Book excerpt: If Hovercraft Can Go Anywhere, How Did We End Up Here? tells the stories of two hovercraft fixers who gave up some of the best years of their lives to repair and commission hovercraft all over the world. Unfortunately, the places that need hovercraft are tough, rugged, god-forsaken and not in the least bit glamorous - just like John and Russ, in fact. Whether impounded in the docks, in pieces in a hanger or strapped to a stranded lorry, as John once put it, "There's always a bloody hovercraft waiting to be fixed."
