They can even come up with very important excuses scientific justification for rocketry experiments. High-altitude measurements of atmospheric something-or-other-i-don't-care-enough-to-research-right-now, aerial photographs to survey for new construction (it's cheaper than hovercraft flyovers, okay?), the possibilities are endless.

And that's even before you consider the hilarity involved in sending, say, Ronan's toaster, on a suborbital trajectory ending in District 12. Beetee can build a missile guidance system so it lands on Haymitch's back porch. The geese are very confused.

(look, I don't think I ever claimed to make sense)
