Which came first, the aeroplane or the Eiffel Tower?

the Eiffel Tower came first, by 14 years. The tower opened for the Paris Exposition Universelle.

Side by side

the aeroplane

The first flight lasted 12 seconds and covered 36 metres — less than the wingspan of a Boeing 747. The Wrights' real contribution was not the engine but three-axis control, which they worked out with a wind tunnel of their own design after finding the published lift tables wrong. Sixty-six years separate that flight from the Moon landing, well within a single lifetime.

the Eiffel Tower

Built for the 1889 World's Fair and intended to be dismantled after twenty years, the Eiffel Tower survived because it turned out to be useful as a radio antenna. It was the tallest structure in the world until the Chrysler Building in 1930. It opened in the same year Nintendo was founded, and two and a half years after the Statue of Liberty it is often assumed to predate.
