And then the terrible speed of the rocket took hold against the forces of gravity and it shot into the heavens, its roaring becoming a fading hiss of sound, the brilliant flash of flame from its exploding tubes, a receding beacon of light that gradually faded to a pinpoint far over their heads.

After the terrific thunder of sound that had accompanied the launching of the rocket, the sudden silence now was almost palpable. The gathered witnesses stood mutely, awe still in their eyes, their ears still ringing with the sound of the takeoff.

Finally the voice of Mathieson broke the quiet night air.

"Well, gentlemen, that's it. Tomorrow morning we'll scout the returned section. It should land somewhere in the open country to the south. We've computed that pretty carefully. I guess that's about all for—"

His voice broke off suddenly and Fred Trent heard what must have distracted the scientist.

A man was shouting from the vicinity of the second rocket, and as they looked, a dim figure could be seen staggering away from the side of the other rocket, coming slowly toward them.

"Good Lord!" Mathieson breathed. "What's that man doing out there? He could have been killed!"

Then suddenly they saw the staggering figure stumble on the ground.

And then Trent and the others were racing across the ground to the side of the fallen man.

When they reached him, Mathieson came forward and knelt beside the figure.
