Transcript for 'Catch Me If You Can'-Style Breach at Philadelphia Airport
A security breach at one of america's biggest airlines, a man posing as a pilot gained access to the cockpit on the philadelphia runway. This is a story straight out of "catch me if you can." Thankfully they did. Abc's david kerley is tracking the latest at reagan national airport for us this morning. Good morning to you, david. Reporter: Good morning, josh. It was supposed to be a flight from philly to florida. You know, usually when you're on the plane you hear this is the captain speaking, well, it wasn't in this case. The man nabbed right before they took off and like you said it sounded just like the movie "catch me if you can." In the movie the character lee FAR die DiCaprio gets his way in the cockpit. Frank, john larkin, the co-pilot. Reporter: But philippe jernnard found out the hard way it's not as easy as it looks. Jernnard was wearing an air france pilot's uniform when he tried to board a flight in philadelphia. He was a ticketed passenger and asked to are an upgrade. Portrayed himses a pilot and made -- gained access to the cockpit. Reporter: Jernnard reportedly SAID HE FLEW 747s FOR AIR France. Showed what appeared to be an air france crew member i.D. And sat down in one of the cockpit jump seats but when the real pilot boarded the flight he questioned jernnard's credentials and police removed the alleged impostor. It's disconcerting because we don't know what his designs were. He could be anything from just wanting to take a look at the cockpit to some other criminal designs. Reporter: While cockpit doors are locked during flights since 9/11, they're usually open during the boarding process. And we certainly don't want anybody up there who is not supposed to be there. That's up to the pilots to make sure that happens and they performed perfectly in this instance. Reporter: This morning jernnard is being held on a million dollars bond. Here's what he's charged for. Are you ready? Criminal trespassing, false impersonation, forgery, false identification to law enforcement and breaking into a structure.
