stricken time. thank you for being here. we heard from the search and rescue agency. they said the early trajectory is the plane is at the bottom of the sea. they say the coordinate given to them is the middle of the sea. when they talk about this coordinate are they talking about the last radio transition in. right. also information sent through the secondary radar that tells what location the aircraft was, what direction and is the flight speed of the aircraft at the time they lost communication. the search area is any type of area that it could have gone to from that point. mary i imagine this is very little comfort to the family members. you ve represented families and victims after airline disasters. what kind of significance does a statement like that have to them? well it s a terribly devastating statement.
this morning about the flight speed. so joining me to talk about this is cnn meteorologist chad myers, also director of special projects at oceanic institution, chad i want to start with you with this latest information we are getting, reportedly a screen grab from air traffic control which show this flight 8501 rising in altitude perhaps rising too slowly at that altitude why would that be a concern? let s break this down for you. i m going to take you where you are at 36,000 feet and give you a division number for how much air is up there. you go to the top of the mountain there is not much oxygen up there. there is 25% of the air at the surface. if that plane was going 353 knots, multiply that by 25%. they expect that airplane to fly at 100 miles per hour at the
information. radar data when the plane was in the south china see, crossing over the straight of malacca, how fast the plane was going. it is wildly significant how fast the plane was going in their calculations. remember, they are using that ping data from the satellite system to try to figure out triangulate where the plane was. that makes it worse if you say this isn t new information because that means that we have lost three weeks. if indeed this is the new area, we have lost three weeks. and that three weeks matters because there is so much time on that black box pinging. we could have been three weeks ago looking in the right area. if this indeed turns out to be the right area and maybe find the black box. that s true. there is no denying that. what it really speaks to is that this is a guestimate. they will admit to you the information they have, the flight speed, they do not know what the plane did, especially after it left the gulf of malacca. did it speed up or slow down
it is quite a different area. so if we are thinking of the area where the debris were before, it can hardly be the same debris. it is not impossible for it to travel that far but practically i don t think it could happen. so we are looking at essentially a different area. and if it is indeed the area, everybody was looking at before and that should be a different set of objects unrelated. absolutely. what about what they re saying as far as the reason they are relocating this search. due to the fact they have new information about the flight speed of this airplane. that meaning that the flight ended much earlier than they thought.
flying planes. thanks, doug. thanks, guys. we want to take a look at the anatomy of a black box. they are built to withstand crashes and can withstand impact. the biggest issue now is the battery life of the black box. the batteries are designed to last 30 days. since we are already on day 12, there are just 18 days left to find the black box. if we take a look back, we can see the underwater locator beacon. as soon as the flight recorder hits the water it begins emitting a ping once a second. and it can transmit from depth as far as 20,000 feet. and the box has some 3,000 prer am ters, airspeed, flight speed and distance. now that we re zeroing in maybe we will be able to do that. robert mark is on the phone with us now. robert, thank you so much for
