why is it possible to turn off the transponder?

does it use a lot of power?

You can turn off everything on an aircraft in case they're starting to ignite.

Also airports would be swamped by transponder messages if they didn't turn them off.

i see - i thought that would be something u want to keep on all the time so the plane can be tracked.

So CBC is still running with the 4hrs of extra flight time (~2500 miles) from engine data. Hasn't that been discredited already too?

Seems they're should be a better way of safeguarding the plane than allowing its transponder to be turned off without other issues.
 
It could literally be anywhere within a flight circle centered at Kuala Lumpur and a radius distance of the gas mileage.

I'm digging on someone stole it idea. They figured out a way to knock it off ATC radars and weaved around well known military radar space and dumped it somewhere. Hell, if that happened, they could've landed it, offloaded the people, refueled, and took off again.

Now I'm really grasping. :)

Such an odd and scary event has transpired. I have no clue what to make of any of this information.
 
Mark my words...

Putting all together...there was a catastrophic failure.

  1. Transponders went off.
  2. There was a cabin decompression.
  3. They all passed out.
  4. The plane flew for several hours until it ran out of fuel and crashed somewhere in the world.

Could also be a major struggle in the cabin due to hijackers then the decompression.

If you remember. Few years ago there were these guys in their way to play golf and their private jet suffered a decompression and all aboard passed out. The plane was scrambled by the Canadian Air Force if I remember correctly and escorted the plane until it ran out of fuel. Pretty sad...

Malaysia said that Boeing/RR said that it was false; however, AFAIK Boeing/RR have NOT themselves publicly commented on the veracity of the claim.

Yeah, it might have been another 'ghost' auto-pilot scenario. Scary as hell if anyone was alive for the duration of that ride. :/

CNN has been running that too, but included a text point that MAS has discredited that information. News networks care more about generating views than reporting factual news, especially when there are little to no hard facts about an event. It's all 'speculation' and 'inside sources' that let them get away with this bullshit.

Malaysia said that Boeing/RR said that it was false; however, AFAIK Boeing/RR have NOT themselves publicly commented on the veracity of the claim.

I don't see a reason why MAS would say that unless it were true, because if it isn't, there's no way to back out of that lie at all.

Why hasn't Vietnam said anything? Malaysia claims that the plane went off radar at the handoff point with Vietnam. Crazy coincidence that the plane transponders went off right at the handoff point.

I'm assuming Vietnam never saw the plane on radar.

They've declined to comment, but WSJ did quote an unnamed Boeing executive as saying “The disappearance is officially now an accident and all information about this is strictly handled by investigators.”, which does imply that they have no evidence suggesting otherwise.

I think what ever happened will either be mundane or go to the wth? End of the spectrum, I mean once they locate the plane..

I hope somehow it landed ok land and there are survivors.

U.S. officials have an "indication" the missing Malaysia Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.

It will take another 24 hours to move the ship into position, a senior Pentagon official told ABC News.

"We have an indication the plane went down in the Indian Ocean," the senior official said.

The official said there were indications that the plane flew four or five hours after disappearing from radar and that they believe it went into the water.

As always, the most logical explanation is typically the most accurate.

Rapid depressurisation and a subsequent incompetent search and rescue operation will be the most likely outcome.
 
The one and only Waldo was on this flight. No wonder it's missing.

Yep, Occam's razor.

I still wonder if those reports about the engine data were more accurate than Malaysia could confirm. Technically the data belongs to the airline and neither RR nor Boeing could comment about it without permission.

If they are moving assets they must have what they would consider solid intel. If this is the case then the plane must have turned back.

Yes. That would make sense. The WSJ article seemed pretty confident.

WSJ and ABC news are clearly referring to the same "indication", but it is possible that WSJ source was wrong about the nature of this indication. That is, it's based on something other than ACARS data.

the airline is state-run
But the WSJ article implies the data is data that goes to Boeing not the airline.

Seems weird since all reports are implying the ACARS data was normal and then the plane ceased all communication.
 
Once again Richard Quest proves he is the only intelligent person at CNN.

I was watching a interview with him on Monday, I kept getting mad though cause Wolf Blitzer kept cutting the guy off...just so they could go to commercial. He was in the middle of some interesting facts too. So I waited...then they came back and he was gone. Awesome..
 
So how about they pass safety legislation for commercial planes to make it illegal (better yet) impossible to turn transponders off. What good does it do allowing the machine to be shut off? Serious question. I can't imagine any scenario where this would be helpful in anyway. "I know! I'll shut off the only thing the world can track us with!"

Edit: saw someone's explanation above. Still, there should be a way for a control tower to send an override command to shut it back on in an emergency.

Not sure if this has been answered, but is there a reason why black boxes on planes don't have their own emergency beacon that can be accessed via satellite and that cannot be shut off?

Seems like a really simple solution that should be installed into every plane.

Everything has to have a breaker for safety reasons. And maybe our resident air traffic controller can comment but I believe cycling the transponder is done in many cases when being controlled.

Well first of all planes rarely go down. Second of all, if you want it to be able to transmit to a satellite you are going to need a bigger battery. You have to balance battery consumption with beacon emitting time.

The biggest issue is radio waves have extreme attenuation when transmitting in water. Especially salt water. GHz frequencies that satellites use have massive attenuation underwater

I'm betting the indication was a submarine on patrol in the Indian Ocean.
Speculation, but maybe this is why they're sending the USS Kidd to the location even though it's 24 hours away, instead of just letting the closest southeast Asian country know the location.

Currently polling second in Australia's federal election (first in the Gold Coast), this feral may one day be your Bogan King.
"Indian Ocean" is vague and covers a huge spread of ocean, so I guess they're saying it crashed in the Java sea if close by, or if they're basically corroborating the supposed Rolls Royce info then I guess it could have flown all the way past Indonesia and straight into the Indian Ocean depths.

If that's what's happened that would seem like they encountered some serious shit around where the aircraft dropped from radar, tried to do a 180 back, the flight crew was incapacitated, and it autopiloted out into the Indian Ocean until starved of fuel, then went down like a brick.

Still doesn't explain why nobody in picked it up on radar, if it had to cross Malaysia, Thailand, and Indonesia.

The only way to enable an override would still require it to be partially 'on', which would still be bad as far as if the system is screwing with other systems or physically malfunctioning. The most likely scenarios in this case would not have benefited from that kind of override anyway as it won't switch off by itself, if it wasn't manually disabled then no override would be able to enable it anyway as either the plane was destroyed by then or the systems were all dead.

The only situations in which remotely turning on the transponder would be helpful is if someone intentionally disabled it to hide the plane in an attempt to do... something with it. By the time the control tower would be suspicious enough to try and re-enable it, the plane would probably be long out of range anyway.

It's a large, large investment, may not be technically sound, and chances are it would have no benefit for possibly ever.

Reuters: Satellites picked up electronic ping from Malaysian flight MH370 after it lost contact with ground control: source close to investigation
 
Post 9/11 - If the doors to the cockpit are locked... is there anybody in the cabin crew that can gain access to it? Does the purser know the code?

I can't speak for US airlines but over here the cabin crew know the override code and can open the door from outside.

Could have been a highjacking and they wanted to bring the plane to somewhere on the east coast of Africa or in the middle-east... Heck...they could have been aiming for Diego-Garcia too.

At this point anything is possible.
 
So is this now the biggest air mystery since the Valentich disappearance? Thinking about that still gives me the willies. Same with that plane in the 1940s that disappereaed with a final transmission that just kept saying "stendec".

This situation really does seem similar so far. Although, for some reason I have this nagging feeling the plane landed at some remote location like Antarctica.
