A pull on the master lever drew up the ladder and closed the hatch in hydraulic silence. The soft whistle of oxygen escaped from pressurized cylinders. An automatic transmitter broadcast an endless S.O.S. Deep in the heart of the lifeboat, dynamos pulsed with the throb of power. "Now, Curtis," said the voice from the past, "turn the red switch in front of you to 'Fixed Control.' Have you turned the red switch to 'Fixed Control'?

To each other, of course." "Of course," Curtis agreed. "Good luck!" said the voice. "Good luck to you both!" It clicked off then and the lifeboat sped Earthward.
