A single missile from an F-22 fighter jet brought down the balloon at 2:39 pm. Eastern time, using the first available opportunity to bring it down without harming Americans, according to two senior officials who briefed reporters. The F-22 was flying at about 58,000 feet when it fired an Aim-9X Sidewinder missile at the balloon at between 60,000 and 65,000 feet, the officials said. That followed an odyssey that took it into Alaskan airspace on January 28, into a swing over Canada two days later and back over the US on January 31. The overflight had intelligence value to the US by allowing officials to study and scrutinize the balloon and its equipment along the way, a defense official said.
