Falcon/Dragon: COTS+CRS funds to SpaceX $2.1 Bn / 20 tons (and ZERO
astronauts) = $105M per ton to the ISS

so, the "cheap" Falcon/Dragon price-per-ton-to-ISS is OVER FOUR TIMES
HIGHER than the "expensive" Shuttle!!!

also, send seven astronauts with a Soyuz (instead of a Shuttle) will
cost $51M per seat x 7 = $357M

The actual all-inclusive shuttle cost per tonne parked in LEO is
perhaps twice that $600M, or $50M/tonne.
