A held thruster burns every tick it is held for, which is the whole reason the pad exists: the console can only say a key went down, so a thruster driven by it could be pumped and never leaned on. The burn happens on the same tick gravity does, and for the same reason - a sixteenth of a pixel is the smallest step this arithmetic takes, and applied sixty times a second it is an enormous acceleration. On the tick, thrust and gravity are two numbers whose RATIO is the whole feel of the thing. Position still moves every frame; only the acceleration is stepped, and nothing can see that. Two against gravity's one, so climbing and falling are the same speed. Three was the first try and it left the moon after about a second of holding. If there is a pad the console's arrows are ignored, because under a window the same keypress reaches both - the pad as a level, the console as a byte - and a thruster that fired twice for one press would be a mystery to anybody tuning it. q still quits, since a pad has no letter for it. With no pad the arrows still burn once a press, which is the most that can be done down a wire. And break.sh now rebuilds the disk images as well as the binaries. Half the things worth breaking here are SplitBit assembly rather than C, and those live on the fixture disks - so an edit to a .asm file changed nothing the suite could see, and the tool reported that nothing caught the break. That is the exact lie it was written to prevent, turning up in a new place. With the disks rebuilt it catches this one: the lander falls between the two captures instead of climbing.
