Two teenage figure skaters, their mothers, and two former world champions who were coaching at a historic Boston club were among the 14 members of the skating community killed when an American Airlines flight collided with an Army helicopter Wednesday night and crashed into the frigid waters of the Potomac River.

The country’s figure skating community mourned Thursday in the wake of news that young athletes, coaches and family members made up as much as a third of the 60 passengers on the American Airlines flight that crashed into the Potomac River Wednesday night.
