"Well, nothing, really," Granby said, deprecatingly. "Just routine, as I said. People have been known to buy aircraft as scrap and then repair them and re-outfit them."

"Is that illegal?" Porter asked.

"No, no," said Granby hastily. "Of course not. But any ship so re-outfitted and repaired must pass CAA inspection before it can leave the ground, you understand. So we keep an eye on such transactions to make sure that the law isn't violated."

"After three years?" Porter asked blandly.

"Well ... ah ... well ... you know how it is," Granby said nervously. "These things take time. Sometimes ... due to ... clerical error, we overlook a case now and then." He glanced at his partner, then quickly looked back at Porter.

"As a matter of fact, Mr. Porter," Feldstein said in a flat, cold voice, "in view of your record, we felt that the investigation at this time was advisable. You bought a scrap missile and used it illegally. You can hardly blame us for looking into this matter."

"No," said Porter. He had transferred his level gaze to the taller of the two men, since it had suddenly become evident that Feldstein, not Granby, was the stronger of the two.

"However," Feldstein went on, "I'm glad to see that we have no cause for alarm. You're obviously not fitting that up as an aircraft. By the way—just out of curiosity—what are you doing with it?" He turned around to look at the big fuselage again.

Porter sighed. "I had intended to hold off on this for a few days, but I might as well let the cat out now. I intend to take off in that ship this week end."
