THIS MAKES ME PROUD TO BE AN AMERICAN: Man washing massive monster truck mistaken for plane crash. “The Springfield News-Leader reports Darnell had recently raced the vehicle on a dirt course, so it needed to be washed. The vehicle can reach 376 miles per hour and in order to wash the 36,000-horsepower truck, Darnell has to use jet engines, which make a lot of noise and create white smoke. . . . Darnell said he takes Shockwave to truck shows across the country, where it does things like setting stacks of cars on fire or racing fighter planes.”
