a160 helicopter

This might be the big one. BOEING A160 HELICOPTER(Edit) asdfghjkl11 Description: 19feb12 The BOEING A160 continues with developmental flight tests in 2010, but test flights have already demonstrated greater endurance, higher altitudes, more extensive autonomy, and greater payload. The program has ambitious goals of a 2,500-mile (4,000 km) range, 24-hour endurance, and 30,000 ft (9,100 m) altitude. Flights are largely autonomous, with the aircraft making its own decisions about how to fly itself so as to meet certain objectives, rather than relying on real-time human control. Maximum speeds are over 140 knots. The aircraft is 35 ft (11 m) from nose to tail and has a rotor diameter of 36 ft (11 m).[2] Early A160s were powered by modified Subaru automotive engines, but newer versions use Pratt & Whitney PW207D turboshaft engines
