(CNN) -- Rescue crews in Alaska were searching Sunday for an airplane carrying four people, including three park rangers, who were reported missing a day earlier when they failed to arrive at their destination as expected, according to the U.S. Coast Guard.

The Coast Guard, National Park Service and the Anchorage Rescue Coordination Center are assisting in the search for the DeHavilland Beaver aircraft, the Coast Guard said in a statement.

The search is focused between Swikshak Bay and King Salmon in the southern part of the state.

The plane took off from Swikshak Bay at 2:45 p.m. Saturday (6:45 p.m. ET). The group was expected to land in King Salmon about an hour later.
