Chizzy's hand whipped out like a striking snake toward the controls and, as he grasped them, his face went deathly white. For the controls were locked! They resisted all the strength he threw against them and the ship still bore on toward that mocking face that hung above the Earth.

"Do something!” screamed Max. “You damn fool, do something!"

"I can't,” moaned Chizzy. “The ship is out of control."

It seemed impossible. That ship was fast and tricky and it had reserve power far beyond any possible need. It handled like a dream… it was tops in aircraft. But there was no doubt that some force more powerful than the engines and controls of the ship itself had taken over.

"Manning's got us!” squealed Pete. “We came out to get him and now he has us instead!"

The craft was gaining speed. The whining shriek of the air against its plates grew thinner and higher. Listening, one could almost feel and hear the sucking of the mighty power that pulled it at an ever greater pace through the tenuous atmosphere.

The face was gone from the sky now. Only the Moon remained, the Moon and the brush-stroke mountains far below.

Then, suddenly, the speed was slowing and the ship glided downward, down into the saw-teeth of the mountains.

"We're falling!” yelled Max, and Chizzy growled at him.

But they weren't falling. The ship leveled off and floated, suspended above a sprawling laboratory upon a mountain top.
