These people are all lucky to be alive after they had close calls with buses. A school bus driver had to evacuate 50 students from her bus after the vehicle burst into flames on her morning route. Another school bus driver saved a little boy who was choking on a penny by performing the Heimlich maneuver. A couple of teens in Poland learned a hard lesson after one jokingly pushed the other right into the path of an oncoming bus. No one was injured.
