Some skaters, their families, and coaches were on American Airlines Flight 5342 that crashed with a military helicopter on Wednesday night.

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.

Six people associated with Zeghibe’s club in Norwood, Massachusetts, were killed in the plane crash: skater Spencer Lane and his mother, Molly, skater Jinna Han and her mother, Jin, and coaches Evgenia Shishkova and Vadim Naumov, a married couple who were world champion pairs figure skaters from Russia in the 1990s.
