Compressed air turns NZ trucker into human balloon

Steven McCormack was standing on his truck's foot plate Saturday when he slipped and fell, breaking a compressed air hose off an air reservoir that powered the truck's brakes.

He fell hard onto the brass fitting, which pierced his left buttock and started pumping air into his body.

"I felt the air rush into my body and I felt like it was going to explode from my foot," he told local media from his hospital bed in the town of Whakatane, on North Island's east coast.

"I was blowing up like a football," he said. "I had no choice but just to lay there, blowing up like a balloon."

McCormack's workmates heard his screams and ran to him, quickly releasing a safety valve to stop the air flow, said Robbie Petersen, co-owner of the trucking company.
