Authorities now warning there will be serious con consequences for anyone making these threats. Here's ABC's David Kerley. Reporter: The FBI tonight is looking for the anonymous suspect responsible for this. Air France 22, shut down at your discretion, you're going to be there for a while. Okay, shutting down engines. Reporter: An air France jet surrounded at JFK. As it approached the U.S., fighter jets scrambled and watched from a distance as the jetliner landed. Just one of about ten flights in which an unidentified caller made a threat to local authorities about a chemical device on board. Jets landing at five different airports, all fakes. The FBI has to take every one of these seriously? They almost don't have any choice, particularly if the plane is in the air. What are you going to do? You are going to search it. Reporter: Tonight, the FBI is trying to trace back the phone caller. Was the call made in the U.S. Or overseas? Is that person linked to an organization, or just an individual?
