The story claimed that american investigators believe the boeing 777 flew for four more hours after dropping off radar. It says the planes engines automatically sent data about the airliners movement to facilities on the ground. If the report is true, that would mean the plane could have flown more than 2,000 miles beyond its last confirmed location. That is between malaysia and vietnam. Now, the wall street journal says the the u. S. Counterterror officials are looking into whether the plane was diverted with the intention of using it for, quote, another purpose.

Reporter while they denied the wall street journal report, they did not offer any new information as to the whereabouts of the aircraft.

Good morning. Good morning. How can we analyze this wall street journal report . What does it say to your experienced eyes . Its good that we finally have some hard evidence, but this opens up a whole host of new questions. Theres still much we dont know. Apparently we were sent engine data that includes altitude and speed, but not direction or position. So it actually enlarges many fold the potential search area. But the idea that its being denied by the malaysians, and theyre suggesting other sources have denied it, as well, i mean, how do you get some sense of the truth of the story . I would love to talk to rollsroyce and boeing to see what they know and what they make of this story. Let me ask you, if you have a plane that has the responder turned off and yet the plane is flying on for another four ho s hours, what does that mean the pilots are doing . Are they knocked out .

That means pretty large bodies of water, make it very difficult to find, right . It would. Yeah. Its a huge area. Its important that satellite imagery of the entire area be used and examined to narrow the search in any way that can be done. One final question. If rollsroyce is getting data from their engines about how those engines are doing, what else might we learn from that . Well, it would certainly tell us how well the engines are performing, the altitude and speed, so it would give an indication, is this a highaltitude cruise flight, at normal cruise speed, and it helps us know how far they might go, if not exactly where. If you could talk to one person today about this, who would you want to talk to . Rollsroyce and boeing. Two people. All right. Captain sully sullenberger, great to have you here. Thank you so much.
