re: #76 IngisKahn

But only 6 years of not throwing out the rocket after each launch.

The Shuttle recovered all the expensive parts, only the External Tank was disposable. The cost of refurbishment for things like the SRBs was high and the Shuttle itself with its reusable RS-25 (later RS-25A) engines plus the OMS was basically torn down and rebuilt between flights, but the same bits went up again and again, some as many as 30 times.
