Isn't Boeing the result of having many "small enough to fail" aerospace companies actually fail?
I'm guessing not.
Note that too big to fail, and small enough to fail has less to do with the size of the company and more to do with market position and government perception.
It's a difficult space to make decisions in and I think it's difficult to make any broad statements about reliability of product or company. Someone would need to actually run some numbers.
Companies like Pipistrel that are producing innovative aircraft are usually small enough to fail.
Just thinking about that, maybe it's both? A combination of little "skin in the game" and short sighted incentives ("budget efficiencies") that lead to a "lack of imagination"?
How did NASA solve this problem after Columbia?
NASA, despite being part of the US government, faced a much larger risk of being shut down after Columbia (more so than Challenger, since the Cold War was over).
not the best choice of wording. i'm sorry, that's all i can see.
