To find your answer, consider this:
  • The railways have been around in their present form (steam propulsion on metal rails through to diesel and then electric) for about 200 years.
  • Trains run on rails that allow them to go in a predetermined direction and space.
  • Trains only move horizontally forwards or backwards.
  • Train signalling is computerised.
  • Japanese Shinkansen trains travel at speeds of 185 mph (operational not the tests at 275) and the French TGV at 200 mph.
  • Train driving is simpler than aircraft and could be automated.
  • Trains have a human being as the driver.
Now repeat those points for the way that aircraft operate and decide how long it will be before they are fully automated.
