Ok- this a question of "could it ever ?"
Several folks have proposed American funding for Big Dumb Boosters. Think a cloned only slightly updated Saturn V. Problem being that NASA has made "Lawn Ornaments" of all the unused ones they had, then shredded or burned all the project docs. Which included ***ALL** known copies of the software. So even if that mythical "found one complete in a warehouse" scenario were true? We would have to recreate software not only to fly the bird, but to support it. That is quite likely the same level of complexity as writing code for ANY such giant rockets.If we copy a Saturn V or make the not yet hatched Saturn VI. Thus it becomes viable to consider Linux and it's ancillary tool sets
Then again - would you ever be able to find enough coders in any other STABLE viable OS?
