Bell 412

This Helicopter is often dubbed as "Conditioned for all conditions". From searing desert to polar ice cap, the world’s most rugged and reliable medium twin-engine helicopter. A daily workhorse for the most extreme climates on the planet, yet refined in temperament and control. Offering an expansive cabin for flexibility in cargo and personnel, plus dual digital automatic controls for flexibility in future growth. There’s no such thing as mission impossible for the 412.
