Two highly-regarded Russian figure skating coaches whose son recently finished fourth at the U.S. Figure Skating Championships were among those feared dead after an American Airlines flight collided with an Army helicopter and crashed into the frigid waters of the Potomac River Wednesday night.

Some members of the U.S. Figure skating community were reportedly on board a passenger jet that crashed into an Army helicopter.

The ice skating community in Greater Boston is waiting to learn if fellow skaters or coaches are among those killed in the mid-air collision of an American Airlines plane.
