Key Takeaways:

Boeing is pumping the brakes on its experimental X-66 flight demonstrator.

The aircraft—being developed with a transonic truss-braced wing—is on “pause for later consideration” after Boeing proposed to focus on a ground-based testbed, which will instead demonstrate simpler, thin-wing technology, NASA said Thursday.
