Incorrect. I quite accurately pointed out that Findley was incorrect
when he suggested that the Shuttle and the Ares 1 faced the same sort
of problems. The fact is... they *don't.* Shuttle started off as a
vastly more ambitious and complex concept than Ares did.

Ares I/V are most certainly less complex than the entire shuttle system.
But then again, Ares is only to replace part of STS, the launch vehicle
parts (SRB's, ET, SSME's, and other bits needed to tie those together).

The long pole in the tent, last I checked, is the J2-X. Luckily, it's not
nearly as ambitious as the SSME, but then again, who's built J2-anything's
lately? In recent memory, only the linear aerospikes for X-33 were based on
J2 turbomachinery, and I didn't think they built that from scratch. The
challenges won't only be engineering, but manufacturing, testing, and etc.

The biggest unknowns are likely from the components that aren't shuttle
derived (i.e. the J2-X), but I wouldn't count out significant teething
problems with the 5 segment SRB's either.
