said, "Fine morning, fine morning lieutenant. You look fit. Fit, sir. No clouds and a splendid full moon." He felt the call, one which generals too old for command can never resist, to give a young officer the benefit of a wealth of experience but, fortunately, his aide swiftly interposed. The aide was brilliant with the usual aide's enthusiasm for paper glory and distaste for generals. Angel knew him well. The aide, in Angel's day at the Point, had been an Upperclassman, a noted grind, a shuddery bore and the darling of his seniors. He didn't look any better to Angel this morning.

But you are not to risk bringing the maps back personally." They were little enough sure he'd ever get there, much less get back. "You will phone all data back to us. Our tests show that the wave can travel much further than that. Anything you may think important, beyond maps and perhaps geology, you are permitted to note and report.
