Four teenagers have been seriously hurt in a crash between two carriages on a rollercoaster ride at Alton Towers.
Sixteen people were in one carriage of the Smiler ride; the other was empty.
Sounds like some kind of blocking failure? Hopefully everyone comes out of it alright.
It will be interesting to find out the cause (if the cause is ever released).
