< I'll bet that without the Shuttle, that truss assembly (it does look complex) could have been done with existing launch vehicles and assembled from the ISS. Less expensively.
I mean, if they had to do it that way, I have every confidence in their ability to figure it out.

Oh really, how? That was my question. Instead you tittle your post; Duh! like you know it all and then you bark with speculative dog breath like; I'll bet...I mean...I have every confidence...but you don't know how and how much it would cost to figure it all either.

Excuse me Arfy, I didn't know you knew it all, why don't you enlighten me on how NASA could perform the task better/cheaper.

Just wanted to expand my launch knowledge (admits to lazy tactic).
