Capsule

I had similar ideas in regards to the Passenger version of the Heavy
Lift Launch Vehicle described in T.A. Heppenheimer's Colonies in Space.

I saw two passenger compartments back to back over a cargo or baggage
compartment over the fuel compartments. The Flight under control of the
Fly Back or Space Tug which might carry a few select passengers and a
little cargo.

I saw the HLLV passenger craft as One Way up to the space colonies
which would be broken up and recycled with shuttle drop tanks by the
colonies for construction material. With those wanting to return home
either having couches installed in a cabin the Flyback's cargo
compartment or returning shuttles which might carry up special cargo
and then have passenger cabins installed into the cargo compartment
with recycled flight couches and other salvaged equipment from the
HLLV.

Or as an additional option, One Shot Drop Ships manufactured in space
from recycled materials and local resources and then sent back to earth
to be scrapped at a boneyard and recycled or used for artificial reefs
like the log boats of the Missippie river of Tom Sawyer's day.

This is just an idea.
