We used to joke at astronomy conferences that if we stopped by the nearest air force base and snagged a fighter jet we could fund all NSF Astronomy money for the next decade, and the math was probably within 10% tbh.

Someone that was sitting around complaining with us was more familiar with military gear and had some numbers on the cost of training the average fighter pilot. They calculated exactly how many pilot trainings it would take to fund all of NSF Astro for a year. That was nearly a decade ago now, so take it with a grain of salt, but it was in single digits iirc.
