A woman claiming to have a surgically implanted bomb has forced a US Airways flight into a dramatic emergency landing.
North American Aerospace Defense dispatched two fighter jets to escort the jetliner as passengers wrestled her to the ground, the Daily Mail reports.
The US Airways Flight 787 departed from Paris for Charlotte, North Carolina, about 11am local time but the plane was diverted after the woman handed a note to a flight attendant warning she had a device implanted in her body.

The plane landed at Bangor International Airport in Maine just after noon, where the woman was removed and the remaining 179 passengers were evacuated to a secure area.
CNN confirmed reports doctors on board the flight examined the woman but found no scars or wounds indicative of surgery. The woman, a French citizen born in the Cameroon, was travelling alone with no checked baggage and intended to stay in the US for 10 days, the news channel reported.
Passengers aboard the flight told ABC the crew first announced the unexpected landing was due to fuel problems and strong headwinds. Twenty-year-old student Alexa Moore told the news channel she noticed the woman get up to go to the bathroom holding her stomach and that the crew made several announcements asking if there was a doctor on board.
"We didn't know what was going on," Ms Moore said as she watched passengers "jaws dropping" as law-enforcement officials entered the plane. "I thought she probably had like some drugs on the plane but it was just like crazy. I was pretty shocked."
The FBI and Homeland Security Department had placed airports on alert for surgically implanted bomb threats since British intelligence uncovered al-Qaeda plans to use surgically implanted bombs in 2010.
It is not known whether the woman has any links with a terrorist organisation but a federal law enforcement source told CNN the threat does not appear to be terror-related. US officials told NBC the woman appeared to be mentally unstable.
The woman is being medically examined and may face federal charges of interfering with a flight crew, CBS reports.
