Secretary of Defense Lloyd Austin confirmed the Chinese surveillance balloon was taken down by a fighter aircraft as it drifted off the Carolina coast.

"This afternoon, at the direction of President Biden, U.S. fighter aircraft assigned to U.S. Northern Command successfully brought down the high altitude surveillance balloon launched by and belonging to the People’s Republic of China (PRC) over the water off the coast of South Carolina in U.S. airspace," Austin said in a statement. "The balloon, which was being used by the PRC in an attempt to surveil strategic sites in the continental United States, was brought down above U.S. territorial waters."

Austin said military commanders determined downing the balloon while it flew over land "posed an undue risk to people across a wide area due to the size and altitude of the balloon and its surveillance payload."

"Today’s deliberate and lawful action demonstrates that President Biden and his national security team will always put the safety and security of the American people first while responding effectively to the PRC’s unacceptable violation of our sovereignty," Austin said.

President Joe Biden briefly spoke to reporters after the balloon was "successfully" shot down by the U.S. military.

"I ordered the Pentagon to shoot it down on Wednesday as soon as possible. They decided -- without doing damage to anyone on the ground – they decided that the best time to do that was when it got over water outside within a 12 mile limit."

"They successfully took it down and I want to compliment our aviators who did it, and we’ll have more to report on this a little later," he said.

"I told them to shoot it down," Biden repeated when asked if the recommendation came from his national security team. "They said to me, 'Let's wait for the safest place to do it.'"

The Chinese surveillance balloon has been shot down in U.S. airspace, according to a senior U.S. official.

It is expected to land in U.S.territorial waters, the official said, adding that airspace will be reopened once it's in the water.

The Federal Aviation Administration has closed additional airspace to support the Department of Defense in a national security effort. The agency also paused departures from and arrivals to Wilmington, Myrtle Beach International and Charleston International airports.

The Temporary Flight Restriction is now in effect until 3:30 p.m.

A South Carolina woman had a front row seat to the military missile strike on a suspected Chinese spy balloon, describing a "loud boom" that rattled her home.

"It literally just flew right over our development, our house," the witness, Liane Munier of Myrtle Beach, told ABC News. "As soon as I walked outside, I literally looked straight up in the sky and it was right above my head."

Munier said it appeared the balloon traveled just offshore when several military fighter jets swooped in and shot it down.

"I was outside, I was watching it. You saw all the fighter jets flying around it and circling it, you saw all the air streams. I think there were about five of them. I went back inside for a second and all of a sudden the whole house just shook that it was like a loud boom," said Munier, who recorded video of the midair episode on her cell phone.

Munier said she initially thought a TV fell off the wall in her daughter's upstairs bedroom, but when she went back outside, she saw smoke in the sky and "you saw the whole thing deflated."

"I knew they were planning on shooting it down, but I didn't think it would be this soon and this close to land," Munier said.

She said it was a relief to her and many of her neighbors to see the balloon shot out of the sky.

"It was nerve-wracking seeing it fly over," Munier said. "I'm sure the whole country felt like that, not knowing what it was."
