Lost in Saigon

That's not necessarily true. If the descent was very slow, and high altitudes maintained a long time, they would not wake up.

Also, the latest is that they remained at 29,500

Without O2 there, they would not wake up.

If the crew rolled off a few thousand feet in the altitude select and got the plane startd down, that's when they MAY have passed out.

As one of the possibilities in this case has to be pilot action, I seem to recall that the captain had a simulator at his house. Would it be possible that the software on this could show what flight profiles the pilot had been practicing?

GPS

Humble Pax here, sorry if this post has no place here, I do respect leaving it to the experts on here generally. However, I am absolutely flabbergasted that my phone and tablet can be tracked by GPS if they go astray, but according to an article on the BBC planes cannot, and black boxes cannot. Sorry if I have misunderstood and mods of course please delete if this is an unhelpful/useless post.

Good grief.

I and others have said quite some time back that this plane caught fire in such a way, rapidly and severely that it overwhelmed the crew eventually.

We now have a rig worker claiming to have seen an aircraft near its track on fire at the time of disappearance and yet people on here still keep going on about depressurisation, hijacking, terrorism and mobile f***ing phones!

I believe you will find this aircraft went into the sea within 10nm of track relatively intact but probably near vertically and at high speed.
There will be very little left.

See Valujet 592 for an almost exact replay.

And before the pedants say yes but Valujet talked to Atc, yes they did but not every major fire sequence starts the same way and yes it is entirely possible for all communications to be interrupted by fire before the reporting systems were aware of it.

Quite some posts back somebody suggested that they knew this flight was loaded with a large cargo quantity of Lithium batteries? Is that correct?

Apologies if this has been answered already.
When the flight lost contact at 1.30am, it was tracked on primary radar for a further 70 mins. #


With all this military/airforce, have the Malaysians been asked if they scrambled military aircraft to intercept the unidentified flight which actually flew over the peninsula ? If not, why not ?

If you think that man has built a computer system than cannot be hacked, given enough effort and determination, you are deluded.
I have a lot more experience than you do in the IT industry my friend. Please don't try to teach granny how to suck eggs.
As Bruce Schneier put it (he's one of the world's top security gurus): "Any competent security expert can build a system so secure that he or she cannot think of any way of hacking it." But someone else will.

Even if the system isn't connected to anything else, it can be hacked by manufacture/maintenance/user subversion. The most dangerous security error is to imagine your system can't be hacked.

Lot of misinformation regarding what a "hack" actually is. The ability to secure root access is largely a function of a true operating system allowing you to reach a command prompt that will accept an executable file. On a system like an avionics "computer" you have a fundamentally different purpose and architecture entirely. As mentioned by those with an intimate working knowledge even with full access and source code the system is not easy to manipulate.


Certainly not an expert but I'd wager very few entities have the combination of specific system knowledge and expertise to accomplish this, basically it would take major resources at a governmental level.


The real question is would access enable someone with lesser experience to degrade or destroy the system or interfere with the genuine inputs in such a way as to render the system inoperable. This is entirely different then actually hacking the system.

According to governments monitoring the area with sophisticated satellites watching for flashes, explosions, etc....none seen

The scenario is possible that the plane came apart with no fireball and is near where you say.

Never has been a verification about batteries. Just questions

I just don't think so.

Yes!

FREDAcheck, as an IT professional I agree completely with that statement.

Some systems are more robust than others but none anr beyond compromise. As you correctly stated the human who build these systems are a security risk/weak point in their own right.

"If the aircraft descended to FL100 the crew and all the passengers would have recovered from the effects of hypoxia"

Even a slow descent to FL100 would be recoverable.

What part of that is incorrect?

Has the recording of supposed contact with the Naritan bound pilot been examined?
From my understanding this has not been convincingly ruled out as a vital piece of evidence.
Why?

Where is MH370?

Start with a circle centered on KUL and radius A/C endurance.
Now eliminate areas covered by other states civil radar if they confirm no radar trace.
Do the same for other states military radar.
Ask neighbouring states for any reports of A/C wreckage reports on land. This is not a sparsely populated area.
Continue in this vein until most likely area for search established.

An empirical method like this is more likely to produce a result than grasping at straws of 'possible turns' or 'fire in the sky' reports.
At the moment it seems the Malaysian authorities are jumping to solutions and that's never a good thing to do.

even more ominous thought. What if the hijackers need an airplane for some terrorist mission. Possibly something as horrible as loading a nuke on the plane and flying it into some city. That would also explain why no one has claimed the hijacking, they would want to keep this quite until their plan is carried out.
I just can't see that as a possibility. Just grabbed a trade a plane and looked. B747-200 combi $2 million US. Last time I looked 727's were going for under $250K. I would think that anyone that could come up with a nuke would have the scratch to just go buy a plane, and not draw the attention a hijacking would bring.

Your tablet can't be tracked if the wi-fi is turned off. Your phone can't be tracked if it's in 'airplane mode'. Neither can be tracked if they're 2,000m underwater.

Similarly, you can't track an aircraft by ADS if it's not sending ADS messages anywhere, due to transmitter failure or whatever. Had they continued sending ADS messages, we'd already know where they were to within a few tens of miles.

Yes I know who Bruce Schneier is, and yes I agree with the general statement that nothing is unhackable given enough time.

However the basic sanity test of viability still very much puts WiFi / remote control of a Boeing 777 firmly into the Hollywood fiction category. I doubt Mr Schneier would disagree with me there.

Yes. It was so reported in the news. (Boeing, Not sure of RR).

NTSB has a team either on the way or already there. Also reported in the press.

And, again, does anyone know the nominal duration of the Sonar locator beacons ?
The acoustic beacons should last about 30 days underwater. You can find info about them here.

Ture but . . .

mixture, what you say here is true however, a hacker doesn't have to take control of the aircraft to cause an incident.

They could just target specific components of the system (for example disable comms) and cause an accident without actually trying to fly the aircraft.

"Not your typical windows desktop"

Maybe not, but laptop based scanning & sniffing tools will soon expose open ports and capture and analyze traffic going in & out of the server including interfacing app ID's and passwords (even if encrypted). Non-mainstream O/S's did not stop Flame or Stuxnet which were specially crafted to target SCADA systems. It is not beyond the bounds of probability that sooner or later the bad actors will figure out how to craft malware that has been specifically tailored to interface with aircraft borne servers such as the T7.

The prospect of Windows like O/S's being used on the 787 and A340's is even more scary.
