Once again, figure skaters representing the past, present and future of the sport perished in a catastrophic plane crash.

American and Russian figure skaters—including two teenagers—were among the 60 passengers onboard a passenger plane that collided with a military Black Hawk helicopter in a crash authorities believe no one survived.

Shishkova and Naumov, a married couple and 1994 world champions in pairs figure skating, had reportedly lived in the US since 1998, coaching young skaters.

"Several" members of the US Figure Skating world were on the aircraft that hit a helicopter, a statement says.
