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.

A pair of young figure skaters, their mothers, and two Russian coaches were among the 60 passengers on board the jet.
