In January 1996, Bohannan climbed the aircraft to in 41 minutes and 35 seconds, setting class world time-to-climb, absolute altitude and altitude in horizontal flight records.

The retractable wings provide a tremendous amount of lift, allowing the rocket to make a smooth transition from horizontal flight to its required trajectory, says Hampsten.
33.
To take off vertically, the pods were rotated to direct the engine's thrust downward, while for horizontal flight the pods were rotated back to the horizontal.
34.
The perennial problem with engines dedicated to vertical lift is they become mere deadweight in horizontal flight, and also occupy space in the airframe needed for fuel.
35.
"' Powered lift "'or "'powered-lift "'refers to a type of aircraft that can take off and land vertically and functions differently from a rotorcraft in horizontal flight.
36.
He would later accomplish the first full-cycle vertical takeoff, horizontal flight, and vertical landing in a jet aircraft on April 11, 1957 at Edwards Air Force Base.
37.
Also, on 28 July, Captain Robert Helt and his RSO, Major Larry Elliot, broke the YF 12A's altitude record for horizontal flight flying at a sustained altitude of.
38.
During September, the feat was repeated multiple times by both prototypes, transitioning from vertical to horizontal flight and vice versa, including instances in which the auto-stabiliser was intentionally disabled.
39.
Lipkin and flight engineer Bulychov, instructed to test wing flutter at extreme 600 km / h diving speed, were killed in the crash; the aircraft actually disintegrated in horizontal flight.
40.
Rossy claims to be " the first person to gain altitude and maintain a stable horizontal flight thanks to aerodynamic carbon foldable wings ", which are folded by hinges at their midpoint.
