situation but something we are prepared for. >> i know you think about the families of those on board the aircraft as well as those on board this aircraft. and i've talked to several family members who are waiting for word. they are all obviously incredibly appreciative of your efforts as are we. so thank you for talking to us. >> you're very welcome. thank you. let's go back with our panel. david gallo, let me start with you. i want to go back to something you said in our last block about the people you have been talking to who had a lot of experience looking at satellite images. they're twbeginning to raise serious questions about what actually is in those images. can you say more about that? how doubtful are you or they that this is actually something significant? >> well, when i look at those images i see something. i just don't know what it is. and it looks like it could be part of the aircraft. it might be maybe a wing. and therefore has a low profile so would be difficult to pick up with radar.
