but if it did come down, for example more like helios and was able to fly down or not go into the roll, i suppose it's possible it could have landed on the water with less of an impact. but we've seen in other water landings, not like sully who did it without this, but a wing will often clip on a wave and then it will tumble. so it remains to be seen if this is the wreckage how this ended up. so we might get lucky and have big pieces or not. >> well, it does remain to be seen. those planes are on their way. we'll let you know what they find when they find it. our thanks to dave davids, both davids, mary, bill, appreciate it. what if flight 370 is never found? a grim question faced by all those loved ones. what is it like to live without knowing for a very long period of time? i'll talk exclusively to a man whose brothers vanished on a plane 11 years ago.
