Harrowing footage of a 13-year-old boy saving a school bus full of kids has resurfaced, and it's pretty impressive.

A scary situation turned into an act of heroism after a school bus driver had a heart attack at the wheel. One passenger didn't hesitate and jumped into action almost immediately. Not only does the boy recognize what's going on, but he has the wherewithal to take care of the bus, while also trying to give the driver compressions.

This kid saved multiple lives that day when his fight or flight instincts kicked in, and we applaud him for his bravery.
