one-thousandths of a second late. It took two months to repair the damage so the rocket could be tried again. Then it worked perfectly. Everything might have been—should have been—almost certainly had been—foreseen. But the chance of trouble was certainly greatest in the cut-in and cut-out feature that was necessary if the X-21 was to make its flight successfully. "I'm sorry," Furness said elaborately, "that I was more concerned about meeting a situation that bothered the brass than guessing at questions you might raise. I told the general we'd be ready to take off. I'll tell him I was mistaken, that you're not ready." McCauley grew impatient. "Confound it, man!" he protested. "There are patrol ships taking position!

The general was to be there too, for a private talk over the prospects and so on. And I've got a son who's been fairly jumping with excitement over the prospect of meeting Major McCauley, the first man ever to take off in a pure rocket and
