I agree. Boeing, if it cannot find investors to keep it afloat, can simply sell off its IP. There are a considerable number of aerospace engineers who would kill for a fresh start. Look at the recent article on the Colorado startup with their supersonic experiment, or SpaceX. And yes, SpaceX does got a lot from tax payers and there are issues with that, but it's also a case of the State investing in something rather than owning it.
Nationalization for something like an airplane company is terrible idea.
