It was a gray Sunday— no sun— and terrible news broke later in the day, of a seaplane crash in Puget Sound.
The plane was a De Havilland DHC-3 Otter with 10 people onboard, nine adults and one child. The US Coast Guard said the plane was traveling from Friday Harbor to Renton Municipal Airport when it crashed into the waters of Mutiny Bay.
The crash was reported at 3:11 p.m. One body had been recovered and nine people were still missing as of around 9 p.m. The cause of the crash is still unknown.
Update Mon 9/5:
The Coast Guard recovered several large pieces of aluminum and smaller pieces of debris smelling of fuel, but “very little” of the actual plane had been found as of midday Monday, said Scott Giard, search and rescue program director for the Coast Guard in the Pacific Northwest region.
Both the Coast Guard and the Washington Department of Fish and Wildlife sent divers to the island, and the Coast Guard will use an underwater drone to try to find the wreckage and come up with a plan to retrieve any remains from the fuselage.
Officials believe the wreckage is on the seafloor, which is between 150 and 200 feet deep in that area. – from the Seattle Times
Update Thu 9/29:
The wreckage of the floatplane was found on 9/12, on the seafloor. Today, some 80% of the wreckage was recovered off Whidbey Island, as well as an undisclosed number of bodies of the 10 victims. Crews began recovering pieces of the wreckage on Tuesday, and recovery is expected to last several more days.
