Ok this is going to become a pissing contest, what I discussed was, the air frames now can be made much faster, because simulation has brought the time factor a little down. Yes I agree that there are much complex part and I did mentioned the metallurgy problem. You also added your 2 cents over here, together we added a 4.
The point is ... it's not a radical design, the whole things should be bit of a progress, not accepting the tried and accepted methods. If this is the way we are going, boy we ain't flying that prototype even near to 2025.
Shouldn't we supposed to create a jet that actually screams our design. Next thing you are going to see are articles saying how we created nose job jet with half ass'd avionics suit.
