Did you hear a boom in Iowa this week? That might have been these turbines being demolished.

When two wind turbines are knocked to the ground in a cornfield in Nevada, Iowa, and no one is around to hear it, do they make a noise?

Yes, they make a boom loud enough sound for the whole town to hear.

Two wind turbines were demolished in Story County around 4 p.m. Wednesday. Crews from the Nevada Fire Department and Story County Sheriff's Office were on scene to keep bystanders away and captured the towers toppling on video.

A drone team documented the demolition, which is normal for any demolition in the county, Story County Sheriff's Office Capt. Nicholas Lennie told Storyful.

“If you were in the Nevada area [Wednesday] afternoon you might have heard a few loud booms. Two wind turbines were intentionally destroyed without issue,” the sheriff’s office wrote in a Facebook post.

The 25-second video shows a small cloud of smoke at the base of the windmill followed by a cracking sound. The two windmills gradually fell toward each other as they crashed into the field. The video had more than 4,800 views on Facebook as of Friday.

It is unknown why the demolition was carried out, but the two turbines were owned by Goodwind Energy. The Register could not find a contact for the company. The two turbines were 92.8 meters in diameter. Storyful reported that they were recently put up for auction by the Peoples Company, an Iowa-based farm management and real-estate brokerage firm, along with four other turbine sites in Iowa.
