The big changes came in the mid 1950s and 60s, and continued into the
70s. After World War 2, when the military had some time on their hands
and a big pile of statistics concerning component failures, the
industry started to really look at component quality carefully.
Basically, the data from the designs of the 1940s led to a lot of
experimentation and trials in the 1950s, which led to better parts by
the 1960s. The aero industry really pushed things along.
