Searchers are looking for a seaplane with two people aboard that went out for a 20-minute tour near Sitka on Saturday and never came back, the U.S. Coast Guard said.
A red and white Piper PA-18 Super Cub plane left a Sitka seaplane base Saturday night for a 20-minute tour of Katlian Bay and Olga Strait, north of the town, the Coast Guard said in a release Sunday.
The Federal Aviation Administration's Juneau station notified the Coast Guard about the overdue plane.
A Coast Guard helicopter crew searched through the night for the seaplane, with a cutter joining the search Sunday morning, according to the Coast Guard.
It's not clear whether the missing plane was on a commercial tour, said Clint Johnson, the Alaska head of the National Transportation Safety Board.
"Right now the emphasis is on the search," he said.
