- The Golden Gate Bridge: perfectly proportioned, beautiful in every detail and earth-quake proof at the same time.
- Satellite navigation, because it combines spaceflight, electronics and physics in an affordable way that is useful for everybody.
- Concorde: the most beautiful object ever made my humans and in it's time the most technically advanced aircraft.

Max,

how long will these last? (Oops, the Concorde is already gone). There are other engineering achievements, from the olden times:
- The roads of the Roman empire
- The gothic cathedrals
- The Semmering railway
etc.
