Just read an entire Wikipedia page on the B2 bomber. Northrop created all the elements from scratch. Tools, tests, systems, software.

Grew up obsessed with fighter jets and stealth bombers, and it's happening all over again.

That’s incredible and the only part that’s sad is I doubt they could do it again.

Read broadly.  Work tirelessly.  Love deeply.

Rabbit hole confirmed.  I pray their OpSec is as good as it was for the B2.  

Also on the other side of the tech curve, I was fascinated with the B-52 growing up.
