The sensors from the first suspected Chinese spy balloon shot down over the US have been recovered from the Atlantic Ocean, the US military says.
Search crews found “significant debris from the site, including all of the priority sensor and electronics pieces identified”, said US Northern Command.
The FBI is examining the items, which the US says were used to spy on sensitive military sites.
The US has shot down three more objects since the first one on 4 February.
“Large sections of the structure” were also recovered on Monday off the coast of South Carolina, military officials say.
About 30-40ft (9-12m) of the balloon’s antennas are among the items found, according to CBS, the BBC’s US partner.
US officials said the high-altitude balloon originated in China and was used for surveillance, but China said it was merely a weather-monitoring airship that had blown astray.

Since that first incident, American fighter jets have shot down three more high-altitude objects – over Alaska, Canada’s Yukon territory, and Lake Huron on the US-Canada border.
In the Lake Huron strike, the first Sidewinder missile fired by the US F-16 warplane missed its target and exploded in an unknown location, US media reported, citing military sources.
The second missile hit the target. Each Sidewinder missile costs over $400,000 (£330,000).
Officials have said the slow-moving unidentified objects, all of which have been smaller than the first balloon, may be difficult for military pilots to target.
White House spokesman John Kirby said on Monday the three other objects were shot down “out of an abundance of caution”.
