Here's all about the commuter plane crash in Alaska that killed 10 people

Crews were racing to recover the wreckage and the remains of those killed in the crash before expected high winds and snow

Authorities are working to recover the wreckage of a plane crash in western Alaska that killed 10 people while investigators are trying to determine what caused the small commuter aircraft to go down in the icy Bering Sea.

The single-engine turboprop plane was travelling from Unalakleet to the hub community of Nome when it disappeared Thursday afternoon. The Bering Air plane was found the next day after an extensive search. Nine passengers and the pilot were killed.

Crews on Saturday were racing to recover the wreckage and the remains of those killed in the crash before expected high winds and snow.

Here are things to know about the plane crash, which is one of the deadliest plane crashes in the state in 25 years.

The plane was reported missing near Nome  Officials said contact with the Cessna Caravan was lost less than an hour after it left Unalakleet on Thursday. Authorities said the flight was a regularly scheduled commuter trip, and the aircraft went missing about 30 miles (48 kilometers) southeast of Nome.

The wreckage was found Friday by rescuers who were searching by helicopter. Local, state and federal agencies scoured large stretches of icy waters and miles of frozen tundra before finding the plane.

A Black Hawk helicopter will be used to move the aircraft once the bodies are removed, officials said.

Unalakleet is a community of about 690 people about 150 miles (about 240 kilometers) southeast of Nome and 395 miles (about 640 kilometers) northwest of Anchorage. The village is on the Iditarod trail, route of the world's most famous sled dog race.

Nome is just south of the Arctic Circle and is known as the ending point of the 1,000-mile (1,610-kilometer) Iditarod.

The cause of the crash is under investigation  The National Transportation Safety Board is sending people from various states to investigate the crash.

Radar data provided by the US Civil Air Patrol indicated the plane rapidly lost elevation and speed, but it's not clear why that happened, according to the US Coast Guard.

Coast Guard Lt. Cmdr. Benjamin McIntyre-Coble said he was unaware of any distress signals from the aircraft. If a plane is exposed to seawater, an emergency locating transmitter sends a signal to a satellite, which then relays that message to the Coast Guard. No such messages were received by the Coast Guard.

Flying is an important mode of transportation in the largest US state  Alaska's vast landscape and limited infrastructure makes travelling by plane a common thing. Most communities are not connected to the developed road system that serves the state's most populous region.

Some high school teams fly to sporting events against rival high schools, and goods are brought to many communities by barge or by air.

Who was on the plane?  Authorities said all 10 people on board the plane were adults.

Among those killed were Rhone Baumgartner and Kameron Hartvigson. They had travelled to Unalakleet to service a heat recovery system vital to the community's water plant, according to the Alaska Native Tribal Health Consortium.

Identities of the others killed in the crash have not been released.

Other recent US plane crashes also under investigation  The Alaska plane's crash marks the third major US aviation mishap in eight days.

A commercial jetliner and an Army helicopter collided near the nation's capital on January 29, killing 67 people.

A medical transportation plane crashed in Philadelphia on January 31, killing the six people on board and another person on the ground.
