The Otter and Twin Otter have been used as self-loading forest-fire fighting waterbombers, flying paddy wagons in police manhunts, and inter-urban airbuses. Otters were bought by the US Army because they could out-perform helicopters and US Navy Otters mapped Antarctica. Otters have made both war and peace, as front-line supply haulers in Vietnam and as the backbone of the United Nations peacekeeping efforts in the Middle East. Lavishly illustrated, Otter & Twin Otter features two of the world's great aircraft with a compelling cast of characters -- the engineers, test pilots and bush pilots who have made the Otter and Twin Otter aviation legends.
