correspondent joins me now to sift through some of the more credible theories here. i want to get to the size and the dimensions one more time. we have to try to understand this. while we don't know what it is, are those dimensions within range of it being a piece of the plane? >> it's pretty big to be a chunk of a plane. the long direction, almost 100 feet. that's the distance from home plate to first base. it's a good throw. on the other hand, the wing is about that. the wingspan of a 777 is 200 feet. >> right. >> one wing, that would match up. a wing, by the way, is something that didn't have fuel in it and might not have because they were running off the center fuel tank, would float. there's a glimmer of hope for the investigation, not hope for the families. it's sad news for the families, but it could be a piece of this plane. you don't know until you get there. some time is going to go by.
