a type of faster-than-light star drive
He grew aware of the thrum and quiver which meant he was aboard a spaceship running on ultra[-]drive.
A lot of time had rushed past into darkness. Russell had no idea now how long the four of them had been plunging toward the red-rimmed sun that never seemed to get any nearer. When the ultra-drive had gone crazy the four of them had blanked out and nobody could say now how long an interim that had been. Nobody knew what happened to a man who suffered a space-time warping like that.
The ship had only been provisioned to go to Alpha Centauri, scout the system without landing on any of the planets, and return. At ten lights, top speed for the ultradrive, it would take better than three months to get back.
The wreck had no ultradrive capability; it was truly a Slow Zone design.
He kicked into ultradrive again and was soon passing close to the next moon in line, several million miles away.
