U.S. Supreme Court Justice Ruth Bader Ginsburg, who is 78 and has battled cancer, was forced to slide down an emergency chute to evacuate a flight at Dulles International Airport on Wednesday, a court spokeswoman said.

Ginsburg was on her way from Washington to San Francisco and was not injured, said Supreme Court spokeswoman Patricia McCabe Estrada.

A pilot noticed a problem with the engine on the United Airlines Flight 586 and ordered 179 passengers and six crew members to exit, said airport spokeswoman Kimberly Gibbs.

United spokesman Mike Trevino says one person was injured but he didn't have other details.

Ginsburg, the high court's oldest justice, was diagnosed with pancreatic cancer in 2009.

She underwent surgery and chemotherapy for the cancer and was hospitalized on two other occasions last year but is maintaining an active travel schedule that is taking her across the country at least twice this summer.
