2 people remain injured after a TNM&O bus hit a cow just north of Boise City.
The Oklahoma Highway Patrol says it happened as the Dallas to Denver bus headed north on US 287.
The impact sent the bus off the road, through two fences, and into an embankment.
It then became airborne before landing on its wheels in a pasture.
Medical Crews treated and released 11 other passengers.
The crash did not hurt the driver.
