A Minnesota man has been dubbed a "superhuman" after bending the door of a burning car and pulling a driver to safety.
Bob Renning, 52, spotted the vehicle on fire on a busy road and tried to flag down the driver Michael Johannes.
Both cars pulled over but Johannes' vehicle immediately became engulfed with smoke and the electronic locks and windows failed.
The driver from Minneapolis unsuccessfully tried to kick the door down and free himself from the burning car.
Mr Renning rushed to help and immediately began to tear the driver's door towards the ground, causing glass in the window to shatter, before pulling Mr Johannes clear of the flames.
But the fast-acting motorist told the Minneapolis Star Tribune he "has no clue" how he bent the steel door in half.
"I'm just a slightly overweight Air Force Sergeant, for crying out loud," he joked.
Trooper Zachary Hill, of Minnesota State Patrol said Mr Renning had shown "superhuman strength", adding: "I don't think I could take a crowbar and fold the door like he did."
Mr Johannes said: "Thirty seconds later and I would have been done. It was a good thing I didn't have my family in there."
He suffered only slight smoke inhalation and minor cuts from the incident but his car was completely destroyed by the flames.
