What astonishes me is that they built the 747 first, before the small planes. It’s like Airbus’s birth was initiated with the Concorde, then the mass-passenger planes. All with negative timestamps, since we were before 01/01/1970 (joke).
Leaders of that time knew they had to start with the grandest project before cascading for a full range of smaller products; whereas leaders today roll out an MVP and try to grow from there.
It truly was another epoch, the epoch of mass amounts of money and resources, not little optimizations.
