Two teenage figure skaters, their mothers and two world champion coaches from Boston 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.

After the U.S. Figure Skating Championships, some young athletes stayed a couple of additional days for further development.

On board the crashed flight were figure skaters and their families, friends and coaches, U.S. Figure Skating confirmed.
