"What happened, Saunders?" Captain Thompson's heavy voice demanded from the driver's compartment. "Didn't Harkness teach you to shoot?"
"Four of them rushed us right at the gate," Rick answered. "Did we make it inside?"
"Think so. Anybody hurt?" Thompson asked.
"Just scratched a little," Johnny answered.
"Good," Captain Thompson grunted. "Is the righting jack O.K.?"
Rick tested a lever.
"O.K."
"Let her rip!"
"Hang on, Johnny," Rick said. "We're going to right her."
Johnny knew just what was going to happen. A tank turned turtle had meant a dead crew until the righting jack had been attached to each of the tanks. Compressed air pushed out two rods fore and aft and flipped the tank right side up.
