A carnival ride broke apart, throwing three people to their death and leaving one teenage girl injured.
The ride consisted of four large metal arms that spin around an axis, and cars at the end that twirl as well.
One of the arms snapped in two, causing the fatalities.
The men who died were in their 20s and 30s.
The tragedy occurred on the first night of a large fiesta in Madrid.
Carnival Ride Accident Statistics
From 1987 to 2000, for mobile and fixed-site amusement rides combined, there were an estimated 4.5 amusement-ride fatalities per year. In 2002, inflatable rides, such as inflatable slides and bounces accounted for an estimated 2,500 hospital emergency room trips and mobile amusement rides accounting for an estimated 3,000 injuries treated by the emergency rooms. But only 65 of the injuries in 2009 were reported as “serious,” meaning they required some form of overnight treatment at a hospital; this comprised roughly 6 percent of all ride injuries.
