Hi there! Do you like airplanes?
What if I told you… someone wanted to make a plane fly with nuclear power?
That’s like giving a plane a tiny sun inside!

This crazy idea was called Project Pluto!
It was a plan to build a super strong, super fast, nuclear-powered airplane.
Nuclear energy comes from a nuclear reaction.
Tiny atoms split — that’s called fission — and it makes a LOT of heat!
