Boeing's design looks better, but for advantage? We're so far away from having certain key technologies ready that one can hardly tell when this project will go forward.

Most of the technology is here just in different places. Itís more a case of getting the disparate parts to work together as anything else.

A key technology for the airplane is totally unproven, part of it is unproven at scale. There are other, less obvious but still critical, gaps as well.

The only problem with that proposition is the assumption that we know everything thatís been developed for these projects, which by their very natures seems unlikely.

New article with a Boeing illustration of the concept.

Indeed. This isn't a napkin sketch and the work behind it did not just come into existence this week.

All the good engineers going to China? Seems they are making all the bold moves these days. First operational Hypersonic Glide Vehicle in a ballistic missile, DF-17...other examples. Seems the US is falling behind. This model does "look" a little strange. And like someone mentioned why the area ruling. Looks more like a student design project than anything else.

And their (China) hypersonic concept, along with DF-17

The only way you get from "unproven" to "proven" is to build hardware and test.  Waiting around for a miracle to land a "proven" hypersonic aircraft on a silver platter without doing anything will get you nowhere.

You misunderstand me, there are unproven technologies so we can't assess which project is ahead of the other.

However, the development program is vital as it shows what technologies need to be developed, a much better situation than the past where research was thrown without any idea what was necessary.

Heck, I think they should be going faster, make rocket boosted scramjet recon drone in parallel and faster than the combined cycle aircraft. The pentagon should plan for developing a hypersonic system every year to push development that fast, think of 1930s or 1950s development pace. Much if the problems will only be clarified and solved by building and deploying.

I think it's less a matter of "good engineers" than it is having a willingness to accept risk if it means gaining more capability.  "Risk" is a terrifying 4-letter word in the DoD. 
"DARPA Hard"  It ain't what it use to be.

Yes , Lockheed design nothing to see with  China , in hypersonic I think USA is still decade ahead of China, it's still difficult for China to build a jet engine for the J-20 so I don't see them build a TBCC engine.

 B) Goodness  :o mislabelled or did China borrow the sketch.

Nah - they would never do anything remotely like that!!!
