The large diameter payload shroud for use on top of the shuttle ET is
really weird looking. That and the lenticular payloads (20 meter
mirror!?!).

Yeah, I loved that one. Sort of reminded me of another USS Enterprise ;-)

But hey, "these were all proposed!!!! Why didn't NASA BUILD THEM" Sorry,
was channeling someone there for a moment!

LOL!
