The US military reports that it has recovered the sensors from the first suspected Chinese spy balloon that was shot down over the US.
The US Northern Command reported that search teams had discovered "significant debris from the site, including all of the priority sensor and electronics pieces identified.".
The US claims that the items were used to snoop on secret military sites, and the FBI is currently investigating them.
Since shooting down the first object on February 4th, the US has destroyed three more.
Off the coast of South Carolina on Monday, "large sections of the structure" were also found, according to military officials.
According to CBS, the BBC's US partner, some of the items include the balloon's antenna, which is about 30-40ft (9-12m) long.
Chinese officials claimed the high-altitude balloon was from their country and was used for surveillance, but US officials claimed it was actually a weather-monitoring airship that had gotten out of control.
Since the initial incident, American fighter jets have downed three additional high-altitude objects in as few days, over Alaska, Canada's Yukon territory, and Lake Huron on the US-Canada border.
According to US media, which cited military sources, the first Sidewinder missile fired by the US F-16 warplane during the Lake Huron strike was not directed at its intended target and exploded somewhere else. Apparently, the second missile succeeded in finding its target.
Over $400,000 (£330,000) (per Sidewinder missile) is required.
Officials have stated that it might be challenging for military pilots to target the slowly moving unidentified objects, all of which have been smaller than the initial balloon.
The three additional objects were shot down "out of an abundance of caution," according to White House spokesman John Kirby on Monday.
They weren't a "direct threat to people on the ground," he claimed, but they were destroyed "to protect our security, our interests, and flight safety.".
The balloon that was shot down over South Carolina was described as being the size of three buses by officials. .
Officials described the second object as being the size of a "small car" and flying over Alaska. The third object was "cylindrical," and it was over the Yukon. And the fourth, which passed over Michigan, was described as "octagonal" but with conditions. .
According to a Pentagon memo that was subsequently published in US media, the flying object that was shot down over Yukon resembled a "small, metallic balloon with a tethered payload below it.".
Additionally, according to the memo from defense officials, the object that was shot down in Michigan "subsequently slowly descended" into the water after impact.
Inconvenient weather caused a delay in the recovery of the balloon that was shot down on February 4. .
The area where the other objects were blown out of the sky is being searched for debris.
Approximately 3,000 sq km (1,870 sq miles) of "rugged mountain terrain with a very high level of snowpack" were included in the search area in the Yukon Territory, according to the federal police force of Canada on Monday.
Due to their remote locations, the fragments from the incidents in the Yukon and Lake Huron may never be found, according to Royal Canadian Mounted Police spokesman Sean McGillis.
Major-General Paul Prévost of the Canadian Armed Forces claimed that the three most recent objects to be shot down all appeared to be "lighter than air" craft and referred to the object in Lake Huron as "a suspected balloon.".
The military chief also stated that anyone in the public who finds debris should call the police right away.
At a security conference in Munich, Germany, later this week, Secretary of State Antony Blinken is thinking about meeting Wang Yi, the highest-ranking diplomat in China, sources familiar with the talks told US media on Monday.
America's top diplomat postponed a trip to Beijing that was initially scheduled for last week amid the dispute over high-altitude aircrafts.
