These exchanges caused us to revise our calendar, to speed some phases, slow others. Like a perfect dinner, a revolution has to be "cooked" so that everything comes out even. Stu needed time Earthside. We needed canisters and small steering rockets and associated circuitry for "rock throwing." And steel was a problem—buying it, fabricating it, and above all moving it through meander of tunnels to new catapult site. We needed to increase Party at least into "K’s"—say 40,000--with lowest echelons picked for fighting spirit rather than talents we had sought earlier. We needed weapons against landings. We needed to move Mike’s radars without which he was blind. (Mike could not be moved; bits of him spread all through Luna. But he had a thousand meters of rock over that central part of him at Complex, was surrounded by steel and this armor was cradled in springs; Authority had contemplated that someday somebody might lob H-weapons at their control center.)
