Two recent milestones included for their engineering content rather than settled historical weight: computing became a utility, and pattern recognition became a matter of scale.
Three milestones that broke the link between geometric complexity and cost, and then took three decades each to reach certified service.
Seven milestones in roughly a century, after which an engineer could calculate in advance what had previously only been learned by building.
Three projects, three constraints, one lesson: at civil scale the hard engineering is in measurement, power distribution and load path, not in the visible structure.
Four milestones from a two-second rocket flight to a lunar landing, and one fatigue failure that changed how every aircraft since has been certified.
Four milestones in which urban water and waste became one system, and in which the profession learned that a treatment barrier can appear to succeed for sixty years.
Three milestones in which metal replaces masonry as the primary structural material, and in which someone tests it before building with it.
Four milestones in which the compact high-pressure engine and the iron hull between them end the age in which transport meant wind, water and muscle.
Three milestones producing the clearest example of fail-safe design anywhere in this set: a brake that applies itself when its own control system fails.
