re: Ed Wright disses HLLVs
". For example, you'd need to either perform extensive (and expensive) modifications on existing launch facilities or build a new one"
Well - the launch platforms were orig designed for 5 liquid fueled engines and was adapted for STS, and the new HLLV will have 5 liquid fueled engines as well :) Might not be all that different, just cut of the weld's put in in the late '70s .
OK - not THAT bad, but actually, I dont think that's a major expense - certainly no more so than any other mission design.
