A charter plane carrying eight people crashed near Cape Newenham, a remote long-range radar site in western Alaska, killing everyone on board, federal officials confirmed Friday. The crash occurred at the airport serving the isolated military installation, located along Alaska's southwestern coastline.

The Federal Aviation Administration is investigating the cause of the accident. Authorities did not immediately release the identities of the victims or the name of the charter operator involved. Cape Newenham hosts a long-range radar facility and is accessible primarily by air, making it a common destination for charter flights supplying the site.

Alaska's remote terrain and heavy reliance on small aircraft contribute to a disproportionately high rate of aviation accidents compared to the rest of the United States. Charter and bush planes serve as essential transportation links for many communities and installations throughout the state that lack road access.

No survivors were reported. Emergency responders were dispatched to the crash site, though the remote location presented logistical challenges. Further details on the circumstances of the crash, including weather conditions at the time of the flight, were expected to be released as the investigation progresses.
