At 8:45 this morning, a Kenmore plane with four passengers went down in Cattle Pass off the shore of San Juan Island.

After the survivors were found by a kayaker, a Good Samaritan aboard the vessel Northern Rose recovered four people, one woman and three men, in the water. According to San Juan County Sheriff Ron Krebs, all the plane crash survivors are alive with minor injuries and are being treated at a nearby hospital. One person has a slight laceration and the others have possible hypothermia.

“They’re all OK — that’s obviously the best news,” John Gowey, Kenmore Air director of operations, said. “It’s obviously very concerning, and it’s been a difficult day for us here.”

The flight departed from Lake Union at 8 a.m. on Friday, Sept. 30.

The U.S. Coast Guard was notified at 9:13 a.m. by Kenmore Air of an electronic emergency signal for one of their planes. They also received a mayday call from the Northern Rose reporting the plane crash at about the same time.

The visibility in the area is only a quarter-mile.

According to a U.S. Coast Guard press release, crews from the Coast Guard Cutter Henry Blake and Station Bellingham are en route to the scene of the wreck to monitor and mitigate the pollution threat. The pilot reported that the plane sank. The possibility of salvaging the plane is unknown at this time.
