■ A helicopter carrying guides and guests on a skiing trip in Alaska crashed, killing five people.

ANCHORAGE, Alaska — A helicopter carrying guides and guests from a lodge on a heli-skiing trip in Alaska’s backcountry crashed, killing the pilot and four others, authorities said.

The only other person on board was in serious condition but stable Sunday at an Anchorage hospital, troopers said.

The five killed in the Saturday accident were identified as Gregory Harms, 52, of Colorado; Petr Kellner, 56, and Benjamin Larochaix,

50, both of the Czech Republic, and two Alaskans, Sean Mcmanamy, 38, of Girdwood, and the pilot, Zachary Russel, 33, of Anchorage, Alaska State Troopers said Sunday. Hometowns were not immediately available for the non-alaskans.

The five passengers included three guests and two guides from Tordrillo Mountain Lodge, said company spokesperson Mary Ann Pruitt. It was not immediately clear which victims were guests or guides.

Russel was a pilot for Soloy Helicopters, a Wasilla-based company that is contracted by the lodge to provide transportation, Pruitt said.

The Eurocopter AS50 crashed under unknown circumstances about 50 miles east of Anchorage at 6:35 p.m. Saturday, the Federal Aviation Administration said Sunday. Authorities said the crash site was near Knik Glacier.

The lodge is about 60 miles northwest of Anchorage, on Judd Lake. The company website bills it as the longest operating heli-skiing lodge in Alaska, promising deep powder, pristine runs on some of the best mountain terrain in the world. “An unparalleled alpine adventure is only a helicopter ride away,” the website says. Packages start at $15,000 per person.

Soloy Helicopters has a fleet of 19 helicopters providing charter services primarily in Alaska.
