Given that software engineering is part of aerospace engineering, some of it is part of that engineering success. But a key aspect of this is that one does not develop software for airplanes the same way and with the same constraints/goals as other areas of software engineering. If anything, aerospace engineering is a prime example of how software can be made more reliable by tolerating failures instead of relying on it not to fail, to come back to GP's point about failure-tolerant designs.
