The National Park Service says an airplane carrying four people is presumed to have crashed into an Alaska lake shortly after taking off for Anchorage.
The service on Friday also released the identities of the four people on board, including a father and his two teenage children.
Officials said the missing included the pilot, Lyle Longerbeam. The passengers are Scott Blom and his teenage children, Kaitlyn Blom and Zach Blom. All are from Port Alsworth.
The plane left Port Alsworth about 10 a.m. Wednesday and was due two hours later in Anchorage, about 170 miles to the northest.
Authorities on Thursday found items belonging to the passengers in the plane on Lake Clark. The park service says the single engine Piper PA-28 is presumed to have crashed in the water, but no aircraft debris has been recovered.
Searchers planned to return to the area Friday weather permitting. The water depth is about 375 feet in that part of the lake.
