 What was Earth's first Spaceship?
The sight of an Earthman on Vega III, where it was impossible for an outlander to be, brought angry crowds to surround John Crownwall as he strode toward the palace of Viceroy Tronn Ffallk, ruler of Sector XII of the Universal Holy Empire of Sunda. "But then I'm told you're an Earthling. "It was only decided yesterday, back on Earth, that I would be the one to make the trip here. What I meant was that I expected someone from Earth to break through our blockade and come here. "If you wanted someone from Earth to come here to see you, why did you put the cordon around Earth? And why did you drop a planet-buster in the Pacific Ocean, and tell us that it was triggered to go off if we tried to use the distorter drive? "You upstart Earthlings are a strange and a frightening race," he said. There was even serious discussion of destroying Earth out of hand, while it is still possible. While these creatures could by no means be classed among the intelligent races, there was a general expectation, which we reported to the Sunda, that they would some day come to be numbered among the Servants of the Emperor. "You Earthlings, in defiance of all expectation and all reason, have exploded into space. As an Earthling, you have heard of the details of the first expedition of your people into space, of course?" " Heard about it?" exclaimed Crownwall. It had been manned by a dozen adventurous people, captained by Crownwall, and had headed out on its ion drive until it was safely clear of the warping influence of planetary masses. The men of Earth had decided that it should work in theory. They had built the drive—a small machine, as drives go—but they had never dared to try it, close to a planet. To do so, said their theory, would usually—seven point three four times out of 10—destroy the ship, and everything in space for thousands of miles around, in a ravening burst of raw energy. They had quickly located a dozen planets, and one that looked enough like Earth to be its twin sister. They had headed for that planet confidently and unsuspectingly, using the ion drive. Two weeks later, while they were still several planetary diameters from their destination, they had been shocked to find more than two score alien ships of space closing in on them—ships that were swifter and more maneuverable than their own.
