are people who will survive this ultimately, but right now, we don't know of any survivors officially. again, 224 souls on board that aircraft. >> ron mott reporting from london, thank you so much. yes, again, we are hoping there are survivors on board. let's hope the next details you bring will be that. let's bring in tom costello. what are investigators looking at when they see this plane and the flight data recorder possibly when that's that found? >> you're right, the flight data recorder and the cockpit voice recorder, those are critical to picking up. so the egyptian military or whoever is able to recover the wreckage will be clearly focusing on that once they have dealt with the victims of this crash. i think there's a lot -- at this point, this investigation is wide open. so in no particular order they'll look at the weather conditions at the time. at the moment all of those are reported to be -- have been normal and fine for flight.
