A U.S. fighter jet is the subject of an urgent search taking place now off the coast of Italy after an F-16 went missing Monday.

The Air Force says they lost all contact with the jet's pilot yesterday after he radioed in that he was experiencing problems with the craft. New word has also just come in that debris has been found in the Adriatic Sea, which searchers say could be from the jet.

The Italian Coast Guard is helping in the search, and authorities say their number one priority is finding the pilot.
