We all know that the X-35 won the JSF contest which is now in the
strategic
development phase as the F-35. At the time the competition winner was
announced (LM) I wondered why Boeing would scrap their whole concept
rather
than push forward with it.

Money of course. Both aircraft were very far from final production designs.
LM didn't get a $24B (that's Billion) FSD contract for nothing and Boeing
would be betting the company in staggering fashion...just to try and
duplicate Northrop's F-20 strategy.
