'Nostalgia's not what it used to be', so they say, but if this gem of a book is anything to go by that wistful and mysterious emotion is still as powerful and poetic a force as ever. In 'Corsairville', Graham Coster takes us on a mesmerising trip back in time to a briefly flowering golden age filled with adventure and high spirits, the 'lost domain of the flying boat'. Pivoting round the buccaneering tale of the luxurious 1930s Imperial Airways flying boat 'Corsair',' the jumbo-jet of her day, and her crash landing and subsequent heroic rescue from a swampy backwater in the old Belgian Congo (now Zaire), the book is really a finely crafted combination of travel writing and secret history. Coster is documenting his quest, an obsession with these strange old 'floating flying machines' that drives him to seek out their memory across the globe, from Malawi to Miami. There is even an element of suspense - at times towards the end of the book I found myself turning page after page, as if this were a gripping 'whodunit', to see if Coster could really make it back to that speck on the map once known as Corsairville. All the while the tale is enlivened by Coster's engaging analysis of his obsession with the subject of the 'air mariners' and what it says about the complex and often irony laden self image of the British. Using the reminiscences of former passengers and pilots to bring vivid personal detail to the subject, he muses on the odd power of these now mythical beasts to touch people's lives for ever (even those, like himself, born years after the last of these true 'air-liners' were put to the torch), whilst leaving behind them only the faintest of physical traces. The writing is consistently superb, making astute reference to other travel writers as well as poets and even TV shows, and also taking delight in the power of flying boat travel to rescue certain words themselves from numbness (e.g. air-craft, alighting, to be transported). There are also maps and numerous black and white illustrations, some of them quite stunning. And despite its focus on a forgotten futurism from a fading past, the book retains its contemporary perspective. In an age when the environmental damage caused by air travel is growing daily, the ability of the silver flying boats to arrive and depart leaving just a rush of spray and a memory, rather than a three mile concrete runway, seems both relevant and beautiful. Nostalgia is alive and well after all, and this revelatory book shows how we can enlighten ourselves a little with its power.
