A Longer Look at the PT6A-34 Powered Viking 400

An airplane that can go virtually anywhere, do anything, and operate in the most extreme weather—and that could sell for twice what you paid for it after 30 years—might sound like a fantasy. But the iconic DHC-6 Twin Otter, which de Havilland Canada ­produced, fits that description.

When Air Tractor AT-802A, bearing serial #0700 took off last month for its home in Valencia, Spain, the occasion was not just an airplane production milestone.
