...bring it up to date, the Bushmaster will sport more powerful engines, enlarged cockpit windows, a lighter and stronger aluminum-alloy skin, a foot-operated hydraulic replacement of the old Tri-Motor's hand-operated "Johnny Brake," a larger stabilizer and a dorsal fin to reduce yaw, modern trim tabs, and interior rather than exterior control cables...
...awfully slow, but former Astronaut John Glenn, 44, didn't mind a bit. Bumping up the slopes on the T-bar at Stowe, Vt., Glenn pronounced the terrestrial view "beautiful" and prepared all systems for the descent. Thoroughly cured of the inner-ear trouble that caused him to yaw and pitch two years ago, after he whacked his head on a bathtub, Glenn roared down the slopes with perfect balance and later lamented that he doesn't have a chance to practice more, seeing as he lives down around Houston, where he still works as a NASA consultant...
When the Gemini capsule is operating properly, its attitude in orbit can be changed by firing strategically placed thrusters that can roll the vehicle, yaw its nose to one side or the other, or pitch it up or down. Once thrusters have been fired to change the orientation of the craft, however, other thrusters-pushing in the opposite direction-must be fired to stop the motion at the desired point. In the absence of an atmosphere to slow it down by friction, the spacecraft would continue any attitude-changing maneuver indefinitely unless reverse thrust were available to stop...
...roll, and we can't seem to turn anything off," Armstrong informed the shipboard controller, who reported to Houston that Gemini was now "showing' pretty violent oscillations." It seemed to Armstrong that Gemini's No. 8 thruster -one of the small rockets used to turn or yaw the craft-had stuck open and was pushing the craft into an uncontrollable spin, which at one point reached a critical rate of a complete revolution each second...
...wanted to move forward, he merely moved the stick forward; when he wanted to go into reverse, he pulled the stick back; he moved it right or left for sideward motion. In his right hand, he clasped a notched pistol grip that controlled smaller thrusters used to pitch, yaw or roll the Gemini around one of its own axes-maneuvers that could fix its attitude in space. By working both controls simultaneously, Schirra was able to make his spacecraft respond as smoothly as a trained seal. Stafford, meanwhile, was busy with a circular slide rule and a heavily crosshatched plotting...
