Just like the chinese want to run the world with their satellites 5 mins after the plane goes missing, just like the Malay's wont release the cargo list, due to the plane containing microchips/techniques that could have the asians over-run the USA....ABBOTT has jumped on the band wagon thinking that he will gain popularity again, due to the fact that he is searching for the plane. He knows damn well he wont find it, and so does everyone else, and apparently we have the money to do it....but he's cutting our free medical service and giving us a fucked up budget in 2 weeks.<br />USING THIS FOR POPULARITY - its obvious, so that explains why Australia is on the hunt!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9133703253863123050.post-50601033027401120782014-04-20T23:48:12.604-04:002014-04-20T23:48:12.604-04:00my first visit to your blog, Greetingsmy first visit to your blog, Greetingsobat kanker darahhttp://www.obatkankerdarah.info/noreply@blogger.comtag:blogger.com,1999:blog-9133703253863123050.post-41102530010335577032014-04-07T08:50:34.308-04:002014-04-07T08:50:34.308-04:00Cmdr.

William Marks of U.S. 7th Fleet, who is aboard the Ocean Shield, said the towed pinger locator was only about 985 feet deep when it began detecting the pings at one-second intervals. “We were not overly optimistic,” he told CNN by satellite phone from the ship.<br />But after lowering the towed pinger locator to nearly 4,600 feet, the crew was able to get hold of the signal for more than two hours.<br />Marks noted that if the signal was coming from a black box, the signal should get stronger and then fade as the locator passed over the site. “That’s what happened,” Marks said, describing searchers as “cautiously optimistic.”<br />Crews then did a course change and passed back over the area, lowering the towed pinger locator to about 9,850 feet, which Marks called the “optimal depth.” Crews were able to pick up a signal for about 15 minutes, he said.<br />According to Houston, the area where the signals were detected has a depth of about 14,800 feet -- the maximum depth the underwater vehicle can operate in. He cautioned that “in very deep oceanic water, nothing happens fast” and that it could take “some days” to establish whether this is connected with Flight 370.<br /><br /><br />http://www.latimes.com/world/worldnow/la-wn-malaysia-airlines-search-20140406,0,4746324.story#ixzz2yCj0kutcAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-9133703253863123050.post-64578113537948003612014-04-06T17:15:05.917-04:002014-04-06T17:15:05.917-04:00

That is, any object smaller than 6" square is unlikely to be recognized as being possibly from the downed flight unless it is something so obvious as human remains.<br /><br />This brings it to an interesting question. Since the Indian Ocean search only commenced a week after the disaster, any reasonable calculation would have put the debris considerable distance from the crash site if the crash site is accurately predicted to begin with.<br /><br />But in this case, it is clear the crash site was not even known with a great degree of certainty.<br /><br />Here is a question for future Search missions. Since there is really no hope of survivors, would the effort not been better directed at searching for sonar pings during the brief window of time (30 days from crash) that the sonar pinger is known to be functioning?<br /><br />If the goal is to hunt for the pinger, the search area can span a far greater distance (e.g. the width of the probable sonar ping audibility range given the receiver used) and should the aircraft be deployed to search for the pinger?<br /><br />Suppose the sonobouys used can detect the pinger with a high certainty in a 1km wide swath. <br /><br />Would it have been better to drop sonobouys systematically at 1km intervals along the most probable flight path?<br /><br />Recognizing that there is a limited supply of sonobouys, and they are not free, there are still cost constraints here.<br /><br />The question is, would it be a better deployment of resources than the increasingly fruitless search for floating debris and wreckage?<br /><br />Finding the CVR and black boxes offer the chance to learn from the incident and the possibility of preventing a future incident. Plus closure for the next-of-kin.<br /><br />Finding floating wreckage at this point leaves the larger and more important task not done.<br /><br />Understandable emotional needs drive the search for floating wreckage. <br /><br />Hard science, engineering, and technical issues drive the search for the sunken wreckage.<br /><br />It is time to think of redeploying resources.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9133703253863123050.post-45602209723362839002014-04-02T23:08:25.537-04:002014-04-02T23:08:25.537-04:00A lot of questions for the Aussies who are cooordi...A lot of questions for the Aussies who are cooordinating this search.<br /><br />The subs (and surface ships) are slow, cannot cover a lot of territory, and need to be carefully coordinated.<br /><br />If they are searching for wreckage that is floating after this long, it is going to be very far from the site of the crash.<br /><br />On the other hand, if they are searching for the wreck, that is a totally different area that is static -- it does not shift much with currents.<br /><br />Problem.<br /><br />If they are listening (passive sonar) critical to have as much quiet as possible, which is harder for a surface ship to do unless it is using a towed array / boom / sono bouys or the specialized towed sonar that listens for the ping.<br /><br />Technically the black box pinger is good for another week, then it is much more run down and harder to hear.<br /><br />Once the active pinger on the box is gone then it is hard work.<br /><br />Active sonar either on vessel topside or on sub.<br /><br />Ping the bottom, and if the bottom echo returns something interesting, go down and take a look with a ROV or mini sub.<br /><br />Here is where it gets tricky, a regular military sub is not any good for bottom search because there are no windows that look out!<br /><br />There may be external sensors that can peer out --- but will it see much unless bright flood lights are lighting up the area? <br /><br />Most military subs do not have that --- they are not intended for this.<br /><br />So if the military sub finds something, they have to call for help, most likely from a vessel with a ROV to go peer down.<br /><br />Not hopeful that they will find something, as AF 447 which has a tiny search area, took 2 years to find anything.<br /><br />This one.. can easily spend 10 years.<br /><br />Searchers will run out of budget long before that.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-9133703253863123050.post-57827938358537690352014-04-02T13:48:35.536-04:002014-04-02T13:48:35.536-04:00
