Slightly related: I wasn't aware of this until last year, but at one point nuclear-powered jet aircraft were a thing. Think cold-war jets, always ready to counter if the other side strikes, that could stay aloft for a month or more.
The issue is that weight is the enemy of flight, and nuclear shielding is heavy. The US was working on distributed shielding: instead of being centralized around the reactor, messing with the CG, it was spread out.
