Using nuclear drives in atmo? Tsk, tsk, that’s dangerous.

Ah, you humans and your silly fragile immune systems…

Well, considering at the time they were already using nuclear power plants, nuclear furnaces, nuclear-powered vehicles, and nuclear devices to excavate reservoirs, cut tunnels, dig canals, disperse inconvenient mountains, and so forth, no-one was really all that worried about another use for Our Friend, The Atom.

(Especially one that was being tested in the middle of a freakin’ desert many miles from anywhere stuff might fall on.)

It also helped that in their universe, no-one at the time had thought of using them on people. I mean, sure, you could theoretically weaponize a nuclear device, but what would be the point? Everyone knows they’d have no imaginable practical use in warfare, right? What possible use is there for a bomb that completely obliterates the economic value of whatever you’re fighting over?
