In that case it would only take a couple of planes worth of stealing before you jad enough plutonium for at least a dirty bomb if not a nuclear weapon lol.

Like wut? Thorium still needs plutonium to work and plutonium can be used for both cases just as uranium afaik.

Absolutely true, but the consequences of a crash are too dire to ever let this be a thing.

Plus, the ROI on a nuclear plane would be a joke. How you gonna pay for it? Maybe break even after 500,000 flights? :)

And then there's the maintenance and professionals and on and on.
