The story

What makes it different

The TriStar was the engineer's trijet. It could autoland in zero visibility in 1972 — a capability so far ahead of its time that crews demonstrated coast-to-coast flights without touching the controls. Its third engine breathed through an elegant S-duct instead of the DC-10's straight-through tail, and pilots loved it without reservation.

It was also a business tragedy. Its Rolls-Royce engines bankrupted Rolls-Royce, the delay handed the market to the DC-10, and 250 aircraft weren't nearly enough: Lockheed lost billions and never built a civil airliner again.

One TriStar still flies — and it's the best one: Northrop Grumman's Stargazer, which climbs to 40,000 feet and drops Pegasus rockets that carry satellites to orbit. The most advanced airliner of its decade ended up as a spaceship's first stage.
