Maine school bus driver Nathan Philbrick had gone to first-aid training several times in his 14 years on the job, but when it finally came to using it, he didn’t think, he went into “autopilot.” The 47-year-old Philbrick is being credited with saving the life of a choking boy on his bus earlier this week. The Morning Sentinel, reports that Philbrick was driving Tuesday morning in Sidney when he noticed a frantic fifth-grade girl in his rear-view mirror. She pointed to a little boy across the aisle from her, crying, but not making a sound. Philbrick stopped, administered the Heimlich maneuver on the boy he thinks is in first-grade, dislodging a piece of candy from his throat. Philbrick and the girl will be honored by the school district next week.
