Thanks. Now, to tense moments on the tarmac at new york's jfk airport, after an anonymous phone call claimed hijackers were aboard the plane yesterday. The plane was surrounded by policemen, the pilot not told why. And his fury was caught on tape. Reporter: Manage you're a passenger, or a pilot, of a massive jet. You're told to go far away from the terminal. And you're surrounded by cops and emergency vehicles. No one tells you what's going on. One pilot blew his top. A rare moment of frustration and anger from inside the cockpit of an american airlines jet. Tell us what's going on here. American 24 heavy, I still don't have any information. Reporter: It's monday afternoon at new york's jfk airport. An american airlines flight 24 has been just ordered to taxi through a remote part of the runway, along with a finish airplane. The planes are surrounded by emergency vehicles. But the american pilot doesn't know why. They're still on the telephones here. They need to get off the phone and give me some information now. I'm the captain of this airliner. I need information pronto. Reporter: Police had been told hijackers wearing gas masks are hiding in the wheel wells of the jets. The pilot's still unclear about what's happening, becomes angrier. We're surrounded by emergency vehicles. There's a reason for this. Someone has to give us the reason or we're going to evacuate the aircraft. You have 60 seconds. Unless they have a legitimate reason to believe that the crew had been compromised and was under the control of somebody else, I don't see much justification at this particular point of not telling the captain what's going on. Reporter: Both planes were later searched and cleared. No threat was found. Now, of course, nothing out of the ordinary found. American airlines said, we generally don't comment on security issues. And they haven't yet. But this is the captain of the ship. It's probably safe to say that most of the passengers on that plane, and most people listening at home right now, would probably want their pilot to do the exact same thing.
