air force lieutenant colonel ken christiansen. mercial pilot, certified aircraft crash investigator. ken, thanks very much for joining us. you have lots of experience in ocean searches like this one. just how difficult is it going to be to determine -- first of all to find these two objects and determine whether or not they are from the missing airliner? >> well, wolf, first of all they have to find -- you go back out and get eyes on the object that was found for the satellite. they have not done that yet. it's dark there now. and when day breaks they'll go out and look for that again. once they establish a target, they're going to have to fly lower and see does this look like an aircraft piece or part or not. if they have ships out at that point or a ship with a helicopt helicopter, the helicopter might be able to come off the ship and take a closer look. or they'll be deboarding someone in a ship in a smaller boat to verify that. >> because the debris, the pictures that the australians released the satellite images, they're four

ken christiansen, mike will someson, guys, thank you. >>> a desperate search for answers for a familyf the missing flight 370 passengers. we're going to see how those waiting are dealing with the trauma. how are they holding up? remember, 239 passengers and crew members were aboard that flight. marge: you know, there's a more enjoyable way to get your fiber. try phillips fiber good gummies. they're delicious, and a good source of fiber to help support regularity. wife: mmmm husband: these are good! marge: the tasty side of fiber. from phillips. are you flo? yes. is this the thing you gave my husband? well, yeah, yes. the "name your price" tool. you tell us the price you want to pay, and we give you a range of options to choose from. careful, though -- that kind of power can go to your head. that explains a lot. yo, buddy! i got this. gimme one, gimme one, gimme one! the power of the "name your price" tool. only from progressive. i jbut they blacked me out.ht these miles are useless! that's turrible. and all the other dates are triple the miles! triple the miles? that's as useless as c

ken christiansen, former retired u.s.orce pilot, former nasa liaison to the department of security. also steven wood, ceo and co founder of all source analysis. he spent many years in the cia as an image analyst. steven, i'll start with you. you've told us you're not at all surprised the search has taken this long to find even any debris. why is that? why aren't you surprised? >> well, wolf, i think the real challenge is, as many of your guests have been saying, the sheer size of the area where the search has to go on. it's enormous. to put in perspective, if you look at just the imagery that's being collected by a commercial satellites, it would extend from washington, d.c., out to the west, out to cincinnati. or up to the north, up to hartford, connecticut. and to try and find an object that is small, in some cases maybe only a couple feet long, that's a tremendous amount of area to be covered. and to try and find an object. >> ken, you're very familiar with the aviation point part of this story. the reports that the pl

. >> aviation consultant ken christiansen. it sounds it if they'll need something to float on which aircraft can take off and land to be able to do this effectively over long periods of time. you can't have ten hours of round trip flight time and three hours of search time. that's not productive. >> that's correct, but right now, what they're going to do, of course they'll look initially to see if there's any signs of life. so technically still could be a search operation. when they determine, which they will be able to determine from the p-3's, they'll go to 250 feet, to see if there are any survivors. if there are no survivors, they'll confirm that and go to a recovery phase. ships will come in and they'll do that with helicopters and smaller boats. >> we've certainly heard stories of people surviving longer than 12 days. if this is in fact, this boeing 777, if it is in fact, how did it end up in the water? did it run out of fuel? was it intentionally crashed? was the plane hijacked? has it been anywhere else? why did it go

ken christiansen is here and live today in san francisco. esterday afternoon, good to have you back on. try to be a teacher for us, if you could, about the flight simulator. you have worked on one? >> that is correct. >> as a pilot, how much time did you send on the simulator? >> going through training, one hour blocks or up to three hours if you are flying a full mission. >> is it loaded with random air strips? does it show you places you can put a plane down? >> yes, it can. you will have a database of the region you are flying in and the runways in the region you are flying. >> would you ever delete your files on a simulator? does the computer get overloaded? or not? >> yeah, that is a good example. you could, but you would not be able to delete one airport from an area. so you would maybe delete an adjacent region to free up space. >> so that is a common thing or not? >> it is. depending on -- simulators are used by multiple people. if this person is flying in the european region they would have a european database and maybe the next pers
