True to its thoroughbred form, the Bombardier* Learjet* 60 XR easily
outpaces the competition in time-to-climb performance and operating
altitude without compromising a class-leading low operating cost. With
its cutting-edge cockpit technologies and stylishly redefined cabin space,
the Learjet 60 XR business jet speeds passengers across distances of up
to 2,405 nautical miles (4,454 km) with ease.
51000 feet bull shit!!!! Maybe the cabin can sustain that pressure differential but the airplane could never get up that high. Unless you had no interior, little fuel, and ballast in the Mose to keep it within CG.
