Which came first, the aeroplane or the lightbulb?

the lightbulb came first, by 24 years. Edison's carbon filament lamp burned for over 13 hours.

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 lightbulb

Edison did not invent the electric light. Humphry Davy demonstrated an arc lamp in 1802, and at least twenty inventors produced incandescent bulbs before him; Joseph Swan demonstrated one in Newcastle in 1878 and was granted a British patent, which is why Edison eventually had to merge with him as Ediswan. What Edison produced in October 1879 was a bulb that lasted long enough and cost little enough to sell, together with the generating and wiring system to make it useful.
