Key Info
  • Balance in zero gravity
  • Duration: 02:50
  • Footage of a scientist exploring his sense of balance on board the zero gravity 'vomit comet' training aeroplane for astronauts. The concept of the 'vomit comet' is explained, including its parabolic trajectory. The footage shows the presenter becoming 'weightless', and during repeated nose-dives he becomes more and more used to the experience despite his inner ear sense of balance being of little use.
