Hey I got to work on the first two B-2 ships while working for (then) Northrop Corp. in Southern Cal. (now Northrop Grumman). Got to build some really cool manufacturing technology. One of the greatest jobs I ever had. So many inventions had to happen just-in-time to pull it off. At the time, was highly secret and couldn't discuss. I saw many of the secrets revealed on Discovery channel the other day as they chronicled how stealth came to be and the role Northrop played. Still can't believe it when I see them flying.
