US Airman Dies After Being Washed to Sea in Japan Typhoon, Two Missing
A U.S. Air Force airman has died and two more are missing after they were washed out to sea from the coast of Okinawa, Japan, during Typhoon Phanfone, according to a statement from the Kadena Air Base.
The three were washed out to sea from the northwest coast of Okinawa at about 3:45 p.m. local time on Sunday, according to the public affairs office for the 18th wing. The incident is believed to be a result of the typhoon, which made landfall with mainland Japan today.
"An Airman that was found by the Japanese Coast Guard and pulled from the sea was later pronounced dead at a local hospital," according to the base's statement.
Helicopters from Kadena Air Base and the Japanese Coast Guard are continuing to search for the remaining two airmen, though rough seas are complicating rescue efforts, the statement said.
The names of the airmen are being withheld for 24 hours after their families are notified.
More information will be released when it becomes available, according to the Kadena Air Base.
ここのcomplicateはなんでもないような動詞ですが，「com-（共に）＋plicate（折る）」という語源から，さまざまな要素が行動，活動，作戦などを「共に折り重ねる」→「より困難にする」となるわけですね。知っているようでいざというときには使えない用法だと思いました。（bookmark, jr.）
