A major milestone has been reached for a small company hoping to
resurrect the storied de Havilland DHC-6, better known as the Twin
Otter. Viking Air tells ANN its new DHC-6 Twin Otter Series 400
Technology Demonstrator achieved "power on" status this week, in
advance of an official rollout and first flight set to take place
at the end of next month.
With major structural components installed, electronics wired,

Technology Demonstrator is the prototype Series 400 Twin Otter

Viking launched the Series 400 aircraft program in 2007, with
