Just a few selections from that link from other parks - maybe AT isn't so bad...
Big Dipper
On 30 May 1972, one of the trains became detached from the lift chain and rolled back to the station (the anti-rollback mechanism having also failed), colliding with the other train. Five children were killed and thirteen others injured. The ride (the park's main attraction) was permanently closed, leading to the decline in the popularity of the funfair and its eventual closure at the end of the 1974 season.
Turbo Coaster
In December 2002, eight riders were allowed to ride the coaster despite the fact that a 16 ft section of track had been removed for maintenance. The ride operator stopped the train just before it hit the missing section. In 2004, Brighton Pier was fined £37,000 for failing to ensure people's safety.

On May 17, 2006, a 56-year-old park employee was performing safety checks on the train when he was decapitated as the train went into a tunnel.
