The pneumatic, or air-filled, rubber tyre is created by John Dunlop in Belfast. He originally designed the tyre for his son's tricycle, to make riding over cobbled streets more comfortable. The pneumatic tyre was later adapted for use on cars, and is still used to this day.

1972 - Apollo 17 launched

Apollo 17, the final mission in NASA's Apollo programme, is launched. The crew consisted of the astronauts Eugene Cernan, Ronald Evans and Harrison Schmitt, who was the first and only scientist to visit the Moon. The mission broke a number of records, including longest moon landing, and longest moonwalk, and was the last manned mission to the Moon.
