A thrill ride turned truly frightening in Germany recently, when two rollercoaster trains collided with each other on the Fire Dragon ride at Legoland in Bavaria. Thirty-eight people were involved, and 34 of those were injured, two of them severely, the Guardian reports. Legoland, which closed the ride and opened an investigation, says one train stopped and the next train "did not stop completely for until now unknown reasons and made impact" with the first one, the BBC reports.
