The speed craft he and Lang occupied had much the best of it on a straight flight, but, against that, he had to set his inexpert handling. The smaller craft could out-climb, out-maneuver the cabin ship but he had no experience in stunting, especially dangerous at night.

Therefore Lang’s decision was the safest one.

To try to make a landing, Lang evidently concluded, was not wise. He felt that he could take over the controls before that need arose, Bob guessed.

A new complication came, however.

If the cabin ship had the disadvantage of being slower, she had gained an offsetting advantage before they saw her. She was much higher in the air than their craft; she could dive, if her pilot chose, and thus close the distance between them—maybe come down “on their tail,” or ride them to earth, if her pilot proved to be determined to force them to land.

Accordingly Bob opened the throttle wider, and slightly elevated the nose to climb.

Lang, peering upward and to the rear, made a violent, vigorous gesture.

Bob, reading it, understood.

He did not question. Lang called for a sideslip!

Instantly Bob manipulated ailerons and rudder correctly and felt the wind on the cheek toward the lower side of their bank, telling him they were slipping.
