A single passenger bi-plane lost power and tried to land on Interstate 80 Thursday afternoon east of Evanston, where it hit a tractor-trailer carrying pigs, authorities say.
The plane, which was travelling from Colorado to Utah, lost power to its engine shortly before 6 p.m., the Wyoming Highway Patrol said. The pilot attempted an emergency landing on the highway and hit the top of the tractor-trailer's sleeper berth.
Nobody was injured in the crash, according to the highway patrol. The plane was severely damaged.
An investigation into the crash will be performed by the Federal Aviation Administration and the National Transportation Safety Board.
