A Lawrence County school bus full of students on their way to school started on fire Friday, authorities said.
The bus was traveling uphill on U.S. Route 23 around 7:15 a.m. when the students heard a pop, Lawrence County Superintendent Robbie Fletcher said. The bus driver saw smoke at the back of the bus and pulled over.
The 45 students on the bus got out and went behind an embankment. The students included preschoolers through high schoolers.
A few of the high school students "were heroes today," Fletcher said. "A couple of the preschoolers actually froze out of fear, and the high schoolers picked them up and helped them off the bus."
Fletcher saw the smoking bus on his way to work, but he said he saw no flames. "At one point it looked like it was contained," Fletcher said.
Fire eventually spread throughout the bus. Fletcher described the fire as "odd," saying that there was never an explosion, and the fire spread "like a wind-driven brush fire."
No one was hurt. The Kentucky Department of Education will be investigating.
