It might be a start. If I had the money and time, I'd try to do the
research.

I don't know, though I reckon it would be less than 100%.:)

That's $39 billion we don't have to spend again. Overall, I prefer the
Saturn V to the Shuttle because you don't have to worry about reuse. The
goal should be to make it cheap and reliable -- not to make it reusable as
an end in itself.

I've nothing against using proven Soviet and Russian designs, but the Ariane
5 has a habit of blowing up.:@ Plus, it's a very high end launch system.
