Timelines
Era-defining machines in order, each with its one defining trick explained live — the moments a clever idea became the way everyone does it.
Seven cars, 1959–2014: mid-engine, ground effect, turbos, active suspension, hybrid power.
Nine aircraft from the Wright Flyer to the A350 — each one the moment flight changed.
Ten engines, 1876–2012: the four strokes, the deleted spark, the blower, the burble — and the motor that ends it.
