have partly cloudy weather in the mountains and you ve got something else going on that distracts your attention. now, another thing that we learned from mh370, from air asia and several crashes in region is that your emergency beacons are only as good as the maintenance they re on. meaning if you don t change the batteries and check them, that they may not have even had the power to power these emergency locators. it may not mean anything that there wasn t a locater beacon. remember, this is one of the carriers on the e.u. s list of do not fly. david, this was a relatively short flight from jayapura to
we are reaching out for more information from search and rescue. some of it, it appears, may have to wait until tomorrow because it is getting dark. mary schiavo, is that something you would expect so long after a plane is missing or disappear, that the air search would begin the next day? no. it s quite a delay. on the plane you have emergency locators and of course the world learned about the problem of lack of location ability on planes with mh370. but when the plane goes down on land they also have emergency locators that have a signal that can be emitted. it s a very long time to wait because i ve worked many accidents where if you can get to the plane, if it s a downed plane, if you can get to it promptly, there are many, many more survivors depending on the nature of the accident.
malaysian officials, ones that have amplified the grief for the families. we re learning more about the boeing 777 and its flight path. the plane was equipped with four emergency locators designed to go off if it impacted with land or water. it s odd that it did not get picked up by the monitoring system. flight 370 made that turn while in vietnamese air space and its altitude rose to 39,000 feet and stayed there for about 20 minutes as it flew over the malaysian peninsula. our pamela brown has all of the latest developments for us. reporter: now under way, a sixth dive. this bluefin-21 underwater vehicle is still the best hope for finding the missing plane. a fifth dive ended soon after it went into the water. a problem with the navigation system had to be fixed before it
what the source of it is. i wonder if we have human intervention on the radar units. what do you mean? well, going back to the earliest part of this, humans didn t actually see what was on the radar the night of it. they had to go back later and figure out what they missed. we heard earlier the plane went up to 43,000, down to 20, back up to 35, made a smooth, left turn so it had to be on autopilot. i would like to know whose radar is this based on, whose analysis of the radar is it based on to know if it s really true or just another story we re hearing about what the plane might have done in the air. you want to weigh in? yeah. and when you re tracking a plane on primary radar without the tansponder, there is a margin of error. and the further the plane is away from the radar, the higher the margin of error. so we just don t know yet. we ve been reporting and nic reported, there are four of these emergency locators.
sank, water hadn t started coming inside in sufficient quantity to trigger these transmitters to come on. and perhaps by the time the water came in, the aircraft was sinking, therefore the frequencies they were transmitting on the signals weren t strong enough to reach the satellite. i mean, these are the types of conclusions and the analysis that investigators will be placing on this information now. but the source i talked to said it was odd. those were his words. it was odd that none of these four transmitters had come on, erin. nick, thank you very much. with 107 very important reporting coming out of kuala lumpur. richard quest is with me along with aviation analyst arthur rosenberg. let s just start with the emergency locators because that s what nick finished his reporting on. they didn t activate. so obviously that could mean a controlled landing, as he said. it could also mean they were manually turned off. that even possible that you could manually disable those or not? t
