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.

The American Airlines flight, scheduled to land at the Ronald Reagan Washington National Airport, was returning from Wichita, Kansas, and was carrying at least 14 figure skaters who had attended a training camp following the U.S. Figure Skating Championships, AP reports.

Several members' of the U.S. Figure Skating team were onboard the American Airlines plane that collided with a U.S. Army Black Hawk Helicopter over Washington, D.C., the governing body said in a statement.
