I'm with crippen - that Dockland Light Railway used to scare the bejeezus out of me.
I remember seeing a Panorama program many years ago, when UK TV was still black and white. They were doing a story on the Comet or Trident and the typical BEA/BOAC pilot (white handle-bar moustache etc), was asked if planes would ever be able to fly themselves - sans pilot.
"They could do that now", he replied, "but the travelling public wouldn't accept it". How right he was.
Now if they ever trained monkies to steer it to the runway and press the 'Go' button...
