He turned on his own power suit, using a lift of a hundred pounds, which gave him double Morey's acceleration. Quickly he gathered speed that shot him up toward his helpless friend, and a moment later, he had caught up with him and passed him. Then he shut off his power and drifted to a halt before he began to drop again. As Morey rose toward him, Arcot adjusted the power in his own suit to match Morey's velocity. Arcot grabbed Morey's leg and turned his power down until he had a weight of fifty pounds. Soon they were both falling again, and when their rate of fall amounted to approximately twenty miles per hour, Arcot cut their weight to zero and they continued down through their momentum. Just short of the ground, he leaped free of Morey, who, carried on by momentum, touched the ground a moment later. Wade at once jumped in and held him down. "Now, now! Calm yourself," said Wade solicitously. "Don't go up in the air like that over the least little thing." "I won't, if you'll get busy and take this damned thing off--or fasten some lead to my feet!" replied Morey, starting to unstrap the mechanism. "You'd better hold your horses there," said Arcot. "If you take that off now, we sure will need the _Ancient Mariner_ to catch up with it. It will produce an acceleration that no man could ever stand--something on the order of five thousand gravities, if the tubes could stand it. And since that one is equipped with the invisibility apparatus, you'd be out one good invisibility suit. Restrain yourself, boy, and I'll go get a new knob control. "Wade, get the boy a rock to hold him down. Better tie it around his neck so he won't forget it and fly off into space again. It's a nuisance locating so small an object in space and I promised his father I'd bring the body back if there was anything left of it." He released Morey as Wade handed him a large stone. A few minutes later, he returned with a new adjustment dial and repaired Morey's apparatus. The strain was released when he turned it, and Morey parted with the rock with relief. Morey grunted in relief, and looked at the offending pack. "You know, that being stuck with a sky-bound gadget that you can't turn off is the nastiest combination of feeling stupid, helpless, comical, silly and scared I've hit yet. It now--somewhat late--occurs to me that this is powered with a standard power coil, straight off the production line, and that it has a standard overload cut-out for protection of associated equipment. I want to install an emergency cutoff switch, in case a knob, or something else, goes sour. But I want to have the emergency overload where I can decide whether or not an emergency overload is to be accepted. I'd feel a sight more than silly if that overload relay popped while I was a couple thousand feet up.
