The United States successfully concluded recovery efforts off South Carolina on Thursday for debris from the suspected Chinese balloon shot down by a US fighter jet on Feb. 4, the US military said in a statement on Friday.
"Final pieces of debris are being transferred to the Federal Bureau of Investigation Laboratory in Virginia for counterintelligence exploitation, as has occurred with the previous surface and subsurface debris recovered," the US military's Northern Command said in a statement.
"US Navy and US Coast Guard vessels have departed the area. Air and maritime safety perimeters have been lifted."
