The balloon flights, some officials believe, are part of an effort by China to hone its ability to gather data about American military bases — in which it is most interested — as well as those of other nations in the event of a conflict or rising tensions. U.S. officials said this week that the balloon program has operated out of multiple locations in China.
At a news conference on Wednesday, Brig Gen. Patrick S. Ryder, the Pentagon spokesman, said that over the past several years Chinese balloons have been spotted operating over Latin America, South America, Southeast Asia, East Asia and Europe.
