Consider the US space shuttle design. It's probably the most
wrong-headed engineering design ever, and it persisted because
too many billions of dollars and careers were invested into it.
Nobody could admit that it was an extremely inefficient and
rather crazy design.
Hey, this is really OT, but I'm interested in. Why do you
consider it is such a bad design? Because the shuttle is intended
to be reentrant and this is costly? Some other issue?
Is about the design or about the entire idea?
Thanks for answering and I promise to not further hijack this
thread.
