I thought Braille scale was a variation on the observation that 1/48 (or better yet, 1/32) was for guys with thick fingers, as in the parts are big enough that a blind man could put it together. But then going ballistic means going off (like a rocket or an explosion) to some people; becoming unguided (instead of tracking to the target) to others; was launched, didn't light off and fell to earth like a dead weight to a few; or launched, lit off, tracked, and ran out of fuel and fell to earth without hitting anything...
