The U.S. government chartered the plane to fly out diplomats from the U.S. Consulate in Wuhan, where the latest coronavirus outbreak started, and other U.S. citizens. The plane will make a refueling stop in Alaska before flying on to Ontario, California, the U.S. Embassy in China has said. Wuhan is the epicenter of a new virus that has sickened thousands and killed more than 100 and the official said Tuesday that the plane left the city before dawn Wednesday, China time.
