A popular theme park ride was stopped due to high winds. 800 people were in a queue waiting for the ride to open.
Once the ride was re-opened, a safety system was manually over-riden to allow a carriage of people to continue on the track. This resulted in the carriage with people crashing into a stationary empty carriage. Eleven people were left with life-changing injuries.
Robust systems should be in place to prevent manual over-rides of safety systems.
