The thing is, that now it has happened all rides had to be checked and will need to be regularly re checked, to prevent this happening again. Ultimately the american accident was allowed to happen as the showman stopped getting the ride services and checked by KMG, so the arm may not have been inspected to servicing specifications.
KMG have an overall have one of the best saftey record in the industry, as a one off incident that has now been identified and measures put in place, it wont put me off riding one again.
