Alton Towers crash: "human error"
24 November 2015
Human error was to blame for the Alton Towers roller coaster crash on 2 June according to the Staffordshire theme park.
Following an investigation on the Smiler ride, a spokesperson said: "A ride shut down message was misunderstood by staff at the ride. This led to a decision to manually restart the ride, over-riding the control system without appropriate safety protocols being followed correctly."
Although the roller coaster is due to re-open in 2016, Alton Towers states that it will feature an additional level of authorisation so no manual over-rides can occur without a senior member of staff present.
