It was powered by eight Pratt & Whitney J57-P-3 turbojet engines, each producing 8,700 pounds of thrust. The aircraft boasted a combat range of 2,920 miles and a service ceiling of 53,300 feet. The YB-60 suffered from flight control and handling issues and lacked the speed and stability of its Boeing counterpart.

The hourly sequence report showed Springfield had a ceiling of 100 feet obscured, a visibility of 3/8 mile and fog with a surface temperature of 30 degrees F. The forecast at our arrival time at Jefferson City was for a ceiling of 1,200′ overcast with a visibility of four miles in fog. Then my worst fears became reality.

The aircraft exhibited poor directional stability (which was solved through the later addition of a ventral tail fin) at low speeds and oil sometimes splattered on the canopy’s windscreen. On May 18, 1945, the T-31 turboprop was finally ready and by June 11, the aircraft was ready to begin testing with its intended engine at Muroc.

The pilot flyingpulled back the thrust levers, and as a result, over the following 5seconds, N1 decreased from 64% to approximately 43%, where it remained until touchdown. The engine thrust was steady at approximately 43%N1, the TSB report explained. The air speed began to decrease, the TSB report said.

While most of it tends to be hidden away either in the cabin ceiling space or under the cabin floor panels, some of it – particularly the air conditioning riser ducts – is fitted in the cabin walls at certain intervals, making the inclusion of a window at that position impossible.

Air Force and NASA to explore using vectored thrust to transition from vertical and horizontal takeoffs to achieve level flight before making a vertical landing. It was also the first VTOL aircraft to use a jet thrust diverter system for vertical lift. He compared its glide rate to that of a Cessna 206.
