this particular care craft had an issue where it bumped another aircraft on the tarmac and had some damage done to the wing. normally those repairs make the aircraft even stronger this is something i would be focusing on. martha: how about the plane itself? it's a triple 7. it is about 242 feet long and about 60 feet from the belly to the upper, to the top of the plane. what we're hearing is that the water in this region is about 240 feet deep, maybe a little deeper than that in someplaces. it seems almost unfathomable, in those beautiful waters in that area you wouldn't see this plane sitting down there? >> correct. and you've also got some, you know, you always hear about the flight data recorder and voice recorder. i mean as soon as those two boxes hit the water, hit the ground at impact, it send off a beacon. it basically turns on the beacon which can be normally seen for about a couple hundred miles.
