This 2.5 MW Clipper model C-96 turbine, part of NextEra's Endeavor I Wind Energy Center, burned for hours before this video was taken. The video shows the turbine's massive blade fall to the ground after first standing on its end before collapsing into a trail of black smoke and flames. The Endeavor I facility is located in Osceola County, Iowa. The turbines stand 420 feet tall including the 153-foot long blades; rotor diameter of 314-feet (96 meters). The 100 MW facility includes 40 turbines and was placed in service in 2008.

A wind turbine near Grafton caught fire Tuesday, May 22 2012. The flames were strong as the smoke streamed from the tower. Fire crews didn't get close at first because of burning debris falling down. Duration: 1 minute 2 seconds
Turbine components weighing 50-tons fell 246 feet to the frozen ground on Saturday (Feb 20, 2009) when the blades of a turbine under construction east of Waverly caught wind and started rotating at a speed reaching 60 rpm. The hub housing the generating components of the Cannon II turbine and the structure's three 177-foot blades collapsed after spinning for hours at the mercy of the wind, says Waverly Light and Power General Manager Diane Johnson. A gust caught the blades prematurely on Friday because, prior to the installation, they were not turned in a way that would have prevented them from catching wind until construction was complete, according to a press release issued by the municipal utility. "It could have spun for days," Johnson says. On Monday, as the mangled blades lay at the base of the tower, construction crews worked to dismantle the structure's top and middle sections to reinforce the turbine. Crew and neighbors were evacuated overnight until the structure collapsed under its own weight. Duration: 10 minutes
