The first flight of the full-scale New Shepard vehicle — NS1[53] — was conducted on 29 April 2015 during which an altitude of 93.5 km (58.1 mi) was attained. While the test flight itself was deemed a success, and the capsule was successfully recovered via parachute landing, the booster crash landed and was not recovered due to a failure of hydraulic pressure in the vehicle control system during descent.[54][55]
