Big brute that poured a thousand troops into L-City Mike did not see until it chopped off for grounding—a glimpse. He would have been able to see it a few seconds sooner had he been looking eastward with new radar at Mare Undarum site, but happened he was drilling "his idiot son" at time and they were looking through it westward at Terra. Not that those seconds would have mattered. Surprise was so beautifully planned, so complete, that each landing force was crashing in at Greenwich 1900 all over Luna, before anybody suspected. No accident that it was just new earth with all warrens in bright semi-lunar; Authority did not really know Lunar conditions—but did know that no Loonie goes up onto surface unnecessarily during bright semi-lunar, and if he must, then does whatever he must do quickly as possible and gets back down inside—and checks his radiation counter.
