This is true of airplanes no longer made. Like the 757 or 727. It's not "lost" but it's like you said thousands of parts made specifically in a process that took 100 different companies and thousands of different machines to make all the parts and thousands of assembly workers to put together and that knowledge just doesn't exist because how could it? Even if you found all the specs for the tech, I'm sure they exist, you would have to reprogram cnc mills, make custom tools and a thousand other things that nobody knows exactly how to do.
