1 person was killed and 21 others injured in a roller coaster accident in Osaka, Japan.
The accident occured during Childrens Day, part of Japan's "Golden Week" holiday celebration when many families pack amusement parks.
The coaster apparently derailed hitting a guardrail.
The accident could probably have been worse. All of Japan's roller coasters are fitted with walkways that surround the entire track. If the coaster had not hit the guardrail it's possible the entire train could have fallen off the track.
