The US military have recovered sensors from a UFO shot down in the Atlantic Ocean amid fears of a spy balloon.
According to the US Northern Command, a "significant debris from the site, including all of the priority sensor and electronics pieces identified" had been found by rescue crews.
And on Monday, "large sections of the structure" were recovered off the coast off South Carolina, according to the US military.
Among the debris was a huge 30-40ft balloon antenna, which officials believe came from China and had been used used for surveillance.
The sensors and electronic pieces are currently being examined by the FBI after the US said the Chinese materials were used to spy on sensitive military sites.
However, China have denied this suggestion and said it was a balloon used for metrological purposes but had simply blown astray.
American fighter jets have since show down three more mysterious objects including one in Alaska, Canada's Yukon territory, and Lake Huron.
The US Air Force's F-16 jet missile reportedly missed its first attempt to shoot down a UFO yesterday as the mystery object flew over "sensitive sites."
A "small, metallic balloon" was spotted floating over Lake Huron in Michigan, US, on Monday, which President Biden ordered to be shot down.
However, the military missed in its first attempt and had to deploy a second Sidewinder, which hit the target, but it is unsure where the first missile landed over Lake Huron.
It was revealed the US spent nearly $1million (£822,000) on two missile attempts.
According to the Pentagon, the UFO was spotted near the eastern portion of Michigan's Upper Peninsula over Lake Huron before crossing into near "sensitive sites."
US officials told Fox News: "U.S. Air Force F-16 that shot down an unknown object over Lake Huron yesterday missed on its first attempt.
"It’s not clear where the first missile landed. A second Sidewinder air-to-air missile was needed."
Defence Secretary Lloyd Austin said on Monday: "I want to be clear, the three objects taken down this weekend are very different from what we were talking about last week. We knew exactly what that was - a PRC surveillance balloon."
"We're gonna confirm what they are, once we have collected the debris."
It was confirmed the object shot down over Alaska on Friday was the "size of a small car" and not similar to the Chinese spy balloon spotted off the coast of South Carolina.
A huge operation to collect the debris is underway but is taking longer than expected due to weather conditions, according to White House spokesman John Kirby.
He said in a statement on Monday: "'The objects in Alaska and Canada are in pretty remote terrain -- ice, wilderness, all of that -- making it difficult to find them in winter weather.
"And the object over Lake Huron now lies in what is probably very deep water."
Defence Secretary Lloyd Austin assured Americans the objects are not a threat to anyone on the ground.
He revealed: "'I want to reassure Americans that these objects do not present a military threat to anyone on the ground."
