This video describes one of the most advanced military aircrafts that are used in US army. The aircraft was developed by Bell Helicopter Textron and Boeing. It took over $3 billions of R&D costs and over 30 lives of testers. At the same time the aircraft is really unique. While being able to land and take-off as a helicopter from any dry spot on the land, at the same time Osprey is capable of transporting 24 people or 23 tons of cargo to 1600 km withought refuelling at speed of 476 km/h. Such a hybrid of a helicopter and cargo aircraft seems to be extremely efficient for military applications.
