"Exactly," the Commander cut in harshly. "These rockets would be grounded on earth. The generals or admirals would swear that the international situation demanded that they be kept there as weapons of defense; and that would be the end of our work."

"We've got to send back a good, thorough report, something to prove that the Rocket Service can do the job, and that it is worth the doing. And, until the patrol rocket gets back, we can't do it."

"Listen! Do you hear it, Lieutenant? Like a horn?" Hurd's wizened rat face knotted in concentration. "Way off, like."
