Emergency personnel responded to a report of a possible plane crash in southwest Missouri Monday, but did not find what they were looking for.

Instead, the ambulances, law enforcement officers and several other emergency responders came across a man washing his jet-powered semi nicknamed “Shockwave.”

Owner Neal Darnell’s neighbors called 911 after hearing a loud noise and seeing smoke over their tree line.

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.

"We do it from time to time and it will usually generate a couple of 911 calls, but today for some reason it brought out a whole army of emergency vehicles," Darnell said. He also said he doesn't blame the neighbors for being concerned.

A Green County sheriff’s deputy told the newspaper that no citations were issued and that the neighbors had acted in good faith because they believed someone might be in danger.

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.
