Currently (August, 2023), no one is talking about nuclear planes. But, if viable, nuclear airliners may be the best solution for airliner emmissions. Will this idea become popular? Will someone try to develop it?

This question resolves yes if, before 2030, there's a team actively building a nuclear aircraft with the goal of eventually putting a nuclear passenger or cargo aircraft into service, even if development is in very early stages and their no prototype has yet flown (but it has to already be in the process of being built. If it's just in the planning phase it doesn't count). It doesn't count if it's for military aircraft.
