Otter and Twin Otter

Following the success of the Beaver aircraft, the engineers and test pilots who developed it decided to build an airplane that could do everything the Beaver could -- with twice the capacity and payload -- and the Otter was born. The Otter was a great airplane, but why not make it perfect with twin-engine reliability and nosewheel landing gear? There were complications, but the result, the Twin Otter, was another winner. With more than 100 photographs, Otter and Twin Otter is a must for plane buffs.
