I know for a fact there are fighter sized jets that can fly as low as 30mph without stalling or falling out of the air. there's an ugly looking test plane stored at a nearby air museum. wish i could remember the name of the test plane.
Does Zig Forums like airships?

I know Israel doesn't like them.

It didn't use water as a primary coolant, but it did use it as a secondary coolant. The molten lead was used to transfer heat to the water, which prevented flash boiling/explosion of water.
We're talking direct air cooled reactors, as a primary and only coolant.
It's possible, and we've even built some air cooled reactors, the issue is safety. Closed cycle air cooled reactors have a way of setting themselves on fire because they are exposed to oxygen and there is a very high heat source nearby, there are 2 of the 3 elements needed for fire. Either that or shit out radiation if they're open cycle.
If we're willing to ignore the risk of a nuclear radioactive Hindenburg, it could be a good idea.
