Parker had the dazed impression that he saw the big blade jerked away through the air. Then, like a leaf suddenly caught in a violent hurricane, the helicopter began to turn flip-flops in the air.

"Do somesing!" Mercedes cried.

As the ship jumped and began to yaw, she was thrown across the cabin. Jerking, buckling, jumping, twisting, the big helicopter lurched its way toward the surface of the sea below. Cutting the power, Parker leaped from his seat. He knew what was going to happen. He intended to try and be ready for it.


Retch, gripping his seat with both hands, yelled. "We're falling!"

"It's not news to me," Parker answered, jerking open the door to the compartment at the rear. Inside that compartment was a mass of synthetic fabric. Tossed to the surface of the sea, inflated by the self-contained flask of gas under pressure, it would make a rubber raft.

"You've left the controls!" Retch barked. "Do something to stop us. We're going to fall." The man's face was wild with fear as he twisted his head around to see what Parker was doing.

"You damned right I've left the controls!" Parker answered. "We've lost the equivalent of a wing in an ordinary plane. If you know any way to stop a plane from falling you tell me." Working with deft, sure hands, he pulled the mass of synthetic fabric out of its compartment.

"But we've got to get to that island. We've found it. We've got to get there while—"

"If we get there, we'll have to swim," Parker answered. "Personally, I'll consider myself lucky to get there by swimming. Here we go."
