The batty, explosive history of bats in the military and a new idea

The idea being that you wouldn't knowingly jeopardize real plans, by gambling their exposure among an untrustworthy audience, but, since counterintelligence is an understood expense, allocate some funds for seemingly outrageous boondoggles, and see if those secrets circulate.
The bat bomb plan was stamped “top secret” and
assigned the suitably sci-fi code name Project
X-Ray.
Figure there were three types of people that were granted access to the classified information, while it was still classified: those hunting for moles, suspected moles, and authorized individuals kept unaware of the mole hunt, but confirmed as definite non-moles. Assume FDR was probably clued in on the nature of the exercise.Why take it so far? Probably victimization by sunk cost fallacy, plus persistent suspicion and paranoia. Plus, when the time came to retire the project, it might have gained some extra inertia all its own.
So even if it started as counter espionage it may have continued based on results being more effective than initially supposed.
> The project never recovered from this ignominious retreat, and it was canceled in 1944.
It was "cancelled" after a shockingly effective test because the first A-bomb was going to be ready. Multiple projects were going on in parallel. Because bat-instigated fire was still an uncontrollable and unpredictable force to unleash on a population, it was wisely cancelled (the research kept, which is all that mattered) in favor of a more pointed and well-understood system. A big targeted explosion.
I believe the V-1 is still the first "guided missile", i.e. self-propelled.
