My dad was at the Skunk Works for 20 years. He then went on to work at Northrop for a good chunk of time as well. The B-2 was started in the 70s and the maiden flight occurred while I was still baking in the womb. I realize aircraft can live a long time and can be retrofitted and upgraded with modern technology - but all things considered it is old. Not saying ancient is bad, either, but as far as organizations go, org knowledge, handoffs of info and books and writing etc... I am not surprised to see the need for reverse engineering.
