WILLMAR, Minn. — A 40-year-old man is recovering this week after being injured after attempting to jump a homemade rocket bike off of his house roof in Willmar, in west-central Minnesota.

According to a police report, the rocket bike consisted of a pair of skis, a bicycle frame and motorcycle exhaust pipe and was being fueled with Heet, an antifreeze product.

The unidentified man fell approximately 13 feet and apparently hit a fence in the yard during the plunge.

When rescue personnel arrived in the Friday incident, he was on his back on a sled, pushing himself around on the driveway with his feet. He was reportedly swearing and yelling about the pain, according to the report.
