Following the catastrophic failure of two Vestas wind turbines on Feb 22 and 23, 2008, the Danish energy agency requested an investigation into the events. A report was produced by engineers at Risø DTU. Below is the report translated into English. The original report, in Danish, can be accessed by clicking on the link below. A video of one of the failures can be seen here: http://www.windaction.org/videos/14294 . It is important to note that the debris from the first turbine failure which occurred on February 22 spread as far as 700 meters away. Risø DTU is formerly a government research institution under the Danish Ministry of Science, Technology and Innovation.
