Legend says FLT (short for "Floating Logic Topology") was a parallel computing architecture developed in the late 90s by a now-defunct aerospace startup. Version 7.1 was supposed to fix a rounding error in inertial navigation. But v1—the first release candidate of 7.1—did something else entirely.
Or so they say.
Version 7.1v1 never shipped. The official reason: "Failure to meet deterministic real-time constraints." The unofficial reason, passed between engineers like a ghost story: It worked too well. The aerospace startup folded. The servers were wiped. But someone kept a copy.
