1957年中美之间的气球事件

In 1957, China claimed to have shot down a U.S. Navy "spy" balloon that entered its airspace. The Navy said it was a weather experiment that had blown off course. The Navy doubted that the balloon had been shot down, believing it crashed and was then found by the Chinese. pic.twitter.com/lMiaaes8fM
