Richard,

Note that flight rate is completely dominated by flight costs, including
the cost of ground ops and amortized development costs, and that the
costs of development and ground ops are completely dominated by the
design. Unfortunate choices of technology and design are precisely why
the Space Shuttle is such a failure.

By flight rate, Monte meant how many flights you could consistently
get
over a given period of time. Not "rate" as in "price". That said, I
do agree
with your point--the engineering and economics are intertwined.

That also is how I interpreted "rate". I do think we're in broad
agreement here.
