The USA is once again puzzling over a mysterious balloon in the sky - and even lets jets rise. The balloon is very reminiscent of the suspected Chinese spy balloon that was shot down last year.
The military is monitoring the balloon's flight, but so far has not discovered any danger. In February 2023, US President Joe Biden ordered the shooting down of a Chinese balloon over the US east coast. China was suspected of using the balloon for espionage purposes. Beijing denied this, saying the balloon was used for weather research and went off course.
