Four seriously injured after 2 carriages collide on Alton Towers ride

[Didymus 34,380]

From what I read, there was a technical problem so they closed the ride temporarily and sent round an empty car, but then sent a car full of people round before the empty one finished it's cycle, the empty car stopped and the one with people in crashed into it. I'm think it's a mixture of technical fault and human error. 

​Oh like that Gosh.. so sad. I mean that's the last thing you expect having a fun day in a themepark.

Still, I'm happy it only happens on rare occasions It's amazing how much we trust insane inventions omg
