up with the plane coming apart at 31,000 feet. the other thing to look at, some sort of structural failure. that would have caused the airplane to come apart. >> we know investigators have the black boxes. but in your opinion, will that matter? >> this may have occurred so instantaneously, there may not be any helpful data on the black box. what's more important, the wreckage on the ground, is there things like bomb residue? so, the real investigation needs to shift to the ground and desert, re-creating what happened. >> steve, thank you. let's turn now to the extreme weather at home. texas battered by at least six tornadoes, 11 reported across the gulf region. and this video, a camera capturing a twister blowing the furniture off of a patio. parts of the lone star state getting more than a foot of rain.
