> nor your plane

Agreed with car - not sure I agree with plane.

Currently we have fission powered submarines and boats. Putting a fission reactor in a plane would be somewhat suicidal, but a fusion reactor would be mostly safe. A large plane is similar in scale to a submarine.

There was a US project to produce a fission powered plane, starting in 1946: https://en.wikipedia.org/wiki/Aircraft_Nuclear_Propulsion

There were recently some rumours about the Russians producing a nuclear powered cruise missile.

I'm not sure a fusion powered plane would be any less crazy. At least with D-T fusion you have a MUCH higher neutron radiation requiring more shielding. OTOH if the plane crashes there's less worry about nuclear waste spreading over the landscape.

Safe maybe, but still restraining fusion is not something as easy as restraining fission. I'm still betting it won't happen in the next 150 years, even though I'd love to be proven wrong.
