About 20 middle school students were aboard a school bus in Manchester before it caught fire.
According to fire officials, the First Student bus experienced mechanical issues on Henry Street Monday morning.
"It was impressive how quickly it shot up and how much damage it did in a very short period of time," said Peter Gallasso, an eyewitness.
The driver pulled over as soon as a problem was noticed. Once that happened, the engine started to smoke and the students were immediately evacuated.
"My first concern was was anybody on it because obviously a school bus is going to have children on it," Gallasso said. "But when I noticed it beginning to burn, there were no children near it at all.”
Gallasso, who has a middle schooler himself, said he is relieved and comforted to know that the bus driver was prepared and handled the situation calmly and quickly.
"We’re entrusting them with the lives of our children, and we would expect them to be prepared, not that we ever expect them to actually have to do it, but they should be prepared and it was good to hear," he said.
First Student told Channel 3 that it is proud of the driver.
No one was hurt.
The incident remains under investigation.
