Operation: Outer Space by Murray Leinster

It is a matter of record that the American continents were discovered because ice-boxes were unknown in the fifteenth century. There being no refrigeration, meat did not keep. But meat was not too easy to come by, so it had to be eaten, even when it stank. Therefore it was a noble enterprise, and to the glory of the kingdoms of Castile and Aragon, to put up the financial backing for even a crackpot who might get spices cheaper and thereby make the consumption of slightly spoiled meat less unpleasant. Which was why Columbus got three ships and crews of jailbirds for them from a government still busy trying to drive the Moors out of the last corner of Spain.

This was a precedent for the matter on hand now. Cochrane happened to know the details about Columbus because he'd checked over the research when he did a show on the Dikkipatti Hour dealing with him. There were more precedents. The elaborate bargain by which Columbus was to be made hereditary High Admiral of the Western Oceans, with a bite of all revenue obtained by the passage he was to discover -- he had to hold out for such terms to make the package he was selling look attractive. Nobody buys anything that is underpriced too much. It looks phoney. So Cochrane made his preliminaries rather more impressive than they need have been from a strictly practical point of view, in order to make the enterprise practical from a financial aspect.
