Malaysia flight 370 Where is it?

[deuem]

A question that's starting to haunt me also.  I will have to dig to find that answer.  I did run across an article like that somewhere.  The only thing that would bother me is both pilots would have to be in on that if it was manually shut off.  I don't know about the flight deck controls so I cannot answer that question with any intelligence.  I will dig for the answer.

As far as I know on the air bags, the pilots can only deploy them if they wish. They all run on their own supply so there is no way to turn them off all at once. The problem is time, Depending on how much you breath it may only last 10 minutes. 10 minutes is plenty of time to get the plane down to a breathable level. If they stayed high then the bags would run out and all aboard would die from no air to breath. The pilot and co-pilot should have a seperate O2 supply in the cabin, not an air bag but a mask.

I believe that answers the question.  Thanks Deuem!

Flight 370 effort could soon shift from search to recovery

http://www.foxnews.com/world/2014/04/09/flight-370-effort-could-soon-shift-from-search-to-recovery/?cmpid=edpick&google_editors_picks=true

The following is from FOX News Asia...I didn't see a copyright so I will post the text here.

The team of international investigators hunting for Malaysian Airlines Flight 370 has "unquestionably" located the missing jetliner and could soon have high resolution images of the wreck site, an expert in deep sea recoveries of ships and planes told FoxNews.com.

There is virtually no chance that the pings picked up by ships towing sophisticated listening devices could be anything other than signals emitted by the plane's flight data recorder, or "black box," David Mearns, of Blue Water Recoveries, a United Kingdom-based company that holds the Guinness World Record for the deepest ocean recovery and has assisted searches for sunken planes.

See above link for rest of the story...it won't let me copy and paste...but it explains what has been done...why...and what they are doing and why....and what they plan to do.  An Australian gentleman has been heading up this search and he is good from what I can see.  By that I mean he is systematic in his methodology.  Once again show me some parts that can be traced!

An earlier comment from a 777 pilot about a nose wheel fire makes me ponder... could the pilot have climbed to 40,000 feet in an effort to quench a fire? but there were no reports from the pilots' of any problems...

meh...

This is informational regarding the oxygen supply and the length of said supply along with the pressure that is maintained within the cabin and it looks like the 777 has two valves.  Let the people and the drawings on this site answer the question.  Looks like the pilot does have access to the switches...

Could be a possibility but we will only know if we get those black boxes.

Maverick, I remember from the movie the Langoliers they deliberately turned down the oxygen so everyone would pass out so they could cross the rift again... so that made me wonder if the pilot could reduce the pressure or turn the air off...
painless way to get rid of the witnesses, and nothing surprises me about the evils that are committed against hu-mons by fellow hu-mons...

There are other that have said the same thing about losing pressurization by manually throwing the switches.  They wouldn't last long.  On the other hand could the computer system be hacked to perform what needed to be done?  Mystery abounds.....

I can't go for the nose wheel fire. If this happened there would have been a mayday call or at least a hijack squack off the box. Even if a fire killed them all, the plane would just fly on what ever flight path was in the system at the time and crash in route. If he had any control he would put the plane down as fast as he could. Even a soft water landing would be better than death.

On the cabin air, yes thay can control it from up front but the bags are seperate and only last a few minutes. I see they said they could kill the people like this even at 20,000 feet+ so why go 45? faster? 18 seconds and you are dead at 45k ft.

If the plane was on true out of control auto and it started to climb, then it would just continue this until it hit thin air and stalled, then crash. So if it went up there it was under control to get back down. If they had dialed in 45k ft then it would have stayed there until it ran out of gas.

Most of the systems I see so far look very mecanical and most likely are not under control of a computer, they just send signals to it. A plane has many seperate systems that are mechanical in nature with sensors sending info to the main computer, not the other way around.

The flight control or navagation might be almost 100% computer and available to be hacked but other systems on board should be stand alone systems.

Still not adding up! In the article you attached the pilot said that another beacon would have gone off the instant the plane crashed. It did not. So either that beacon failed or the plane made a softer landing. Water or land. A plane that size making a nose dive into the ocean would have split up into a million parts. Yet a nice belly landing could be done and it would float long enough to get off and then it would sink as a whole plane. Many planes have landed in water and been recovered and flown again, as is with little work. The pilot mentioned a few including the hudson river landing.

Getting to a higher altitude to kill the passengers doesn't sound like a sure way, as some people have more resistance to low oxygen levels than others, that's why some people have climbed the Everest without oxygen.

45,000 feet look much more likely to kill everyone, as the Everest, if I'm not mistaken is less than 30,000 feet high.

Forty five minutes at FL450 should be enough to sort out everyone aft of the pilots compartment.

IF the co pilot was either in the back or taking his scheduled rest (I think they have a place for that on the bigger boeings) then very few poeple would be aware that there is a problem, until people started losing consciousness,

I would imagine that a few of the more active and bright souls might get as far as trying to get past the locked cockpit door before succumbing to anoxia, in the last stages, possibly even resulting in the handling pilot having to make some abrupt changes in attitude to clear the corpses towards the rear so as to be able to open the flightdeck door afterwards. He would only be able to do that at lower altitudes for techncial reasons involving aerodynamics, (and colloquially known as "coffin corner") which might be what people report when they are talking about an erratic descent profile. 

But we are assuming that some things we are told are true, and in fact I have to ask, HOW do WE really know that the aeroplane went up to FL450? I hate this conspiracy stuff.

and here is what is going to happen if they do find the black box...nothing will be on it....and how interesting that they are coming forward with this info now...



However when investigators examined the cockpit voice recorder (CVR), they found it had "continued to run for some time after the aircraft had landed and as a result
all relevant recordings were lost."






Malaysia Airlines Lost Black Box Data on 2012 Flightadvertisement
By Henry Austin
As the hunt for missing MH370 continues, it has emerged that Malaysia Airlines lost all the black box voice recorder data from a plane after an engine failure forced it to turn back to London's Heathrow Airport nearly two years ago, a report by British investigators said Thursday.

Shortly after the Boeing 747 took off on August 17, 2012 for Kuala Lumpur, the number two engine failed, findings by the U.K.'s Air Accident Investigation Branch revealed. The crew shut it down and jettisoned fuel before manually landing the aircraft -- with 340 passengers and 22 crew on board -- at Heathrow.

However when investigators examined the cockpit voice recorder (CVR), they found it had "continued to run for some time after the aircraft had landed and as a result all relevant recordings were lost."The CVR records on a continuous loop, so after around two hours it will record over what was previously logged, according to aviation expert Adrian Gjertsen of U.K.-based Airsupport Aviation Services Limited.

The report described the event as a "serious incident."http://www.nbcnews.com/storyline/missing-jet/malaysia-airlines-lost-black-box-data-2012-flight-n76786

Nothing new except they are still trying to home in on those pulses.  I am watching Australian news since they are closer to the incident.

According to John Lear... the base commander at Deigo Garcia told him the plane is not there... he sais we don't even have any hangers big enough to hide it it
