Battling an intensely hot fire after a cargo truck crashed on a highway, emergency crews were surprised to find themselves suddenly fired upon — by corks from exploding wine bottles inside.

"The corks were popping out of the bottles like the old Jiffy Pop popcorn we grew up with," Wyoming Highway Patrol Lt. Scott Keane said. "My trooper got hit in the arm with one."

The fire Thursday was so intense it burned the trailer down to its axles, melted the tires and damaged about 75 feet of pavement.

Besides the heat and flying corks, firefighters also had to deal with shattering bottles.

But Keane says no one was injured, and the truck driver escaped the fire. Keane says the wreck likely was caused by a locked brake or hub malfunction.
