Billy Enright cleared his throat and took a sip of water. "At 1200 hours I was to take off, heading for a small, insignificant Type G-Zero dwarf in Hercules, the exact coordinates I've forgotten for the moment. This star was selected over the more familiar celestial objects because it was closest to the Sun in size and radiation, and therefore many believed that it was most likely to have a set of planets similar to the planets of Sol. I was to test the drive and make observations on the process of exceeding the velocity of light, recording them. I was to approach this star—" "Sixty light years distant?" interrupted Commodore Hogan. "Yes." "An hour's trip each way," said the commodore pointedly. "—I was to ascertain if this star had any planets, and if so, whether there was one at about ninety million miles from the luminary. If this was so, I was to approach and attempt to land. Then contingent upon the success of the previous set of 'ifs' I was to tackle the following. I was to take samples of the air and the water and the ground. I was to measure the temperature. I was to dig up a plant or two and I was to see if I could catch a small animal alive. I was to remain on that hypothetical planet for no longer than six hours. Then I was to take off and return to Earth." "I see. And in the case of emergency, either there or en route?" "I was to turn immediately and return to Earth." "And you did not." "Commodore, may I point out that mine was a mission of rather extraordinary nature? I was a volunteer. Willingly I put myself in a position that no other man had ever been in before. I went into the Deep Unknown, across the limitless depths of galactic space, and my return was subject to considerable doubt. Now, the fact that I have returned at all is in itself a statement of success, even though I may have been delayed." "I am sorry, Captain Enright. But your statements have not yet given us one reason for your delay. In fact, everything you have said indicates that you could, at any time in the past eighteen months, have returned. Instead, you seem to have deliberately remained out of touch with the people who entrusted you to perform a difficult mission." Billy Enright drawled, "Well, not exactly, Commodore. I did send an explanatory message, but that was in deep space and I am afraid that the radio waves will not
