Thanks for another great video! This was a really interesting and useful look back at how we got here. If there's lesson to be learned, it seems to be: the cheaper your manufacturing process, the more launches you'll get to make. More launches means more failures, but it also means more opportunities to hunt down and fix mistakes so they won't happen again. The bigger, more expensive programs either didn't get off the ground, or in the case of Boeing, did launch but with unsatisfactory results. Meanwhile SpaceX has been building (and sometimes losing) cheaper rockets at a much faster rate, and making more progress than everybody else.

That's one those images that will define an era.
