It was killed before it even flew. Imagine if Boeing had undertaken the
777 program, built a dozen prototypes... but then, due to the board of
directors being drunk one day, officially terminated the project before
the first one flew.

"See? Boeing wasted billions. The whole idea of a large two-engine long
range passenger plane is thus a bad one that we should never try
again."


So will the SDHLV be more like the B-47 or more like the Saturn V?
What do you think, Scott?

Difficult to see is the future. A notable difference here is that both
the B-47 and the Saturn V were bleeding-edge technology... HLLV won't
be.
