Beijing-bound MAS plane carrying 239 people missing as of 20 mins ago.

Hmm sealed evidence fishier and fishier by the minute.

Hmm sealed evidence fishier and fishier by the minute.

Sealed evidence being the communications with the plane. Sounds like this is headed towards the scenario mentioned about the pilot hijacking the plane to try to help a political figure. If that is true then I am sure they would not want to release the info. This particular hijacking could very well start a small war if this is the case.

This article points out that based on the ping data the aircraft would seem to have been programmed to the south instead of flying on autopilot after last way point.

Now for an interesting piece of information that does not appear to have been considered in detail. A pilot on PPRUNE pointed out that there are two different modes of operation of the 777 flight management computer. A programmed route will take a straight line (great circle) route to the next programmed waypoint, but if there is no longer any waypoint in the computer, then the plane will fly on a magnetic bearing. While this is not material around Malaysia, it becomes highly significant in the Southern Ocean.

As a result, a magnetic heading would need to start out going significantly further west (and would also fly much further) to end up at the same point as a great circle route.

It is easy to see that in combination with Jeff Wise’s chart of the ping lines, a magnetic bearing heading is highly unlikely to have resulted in the 3.11am ping arc lying outside the 2.11am ping arc. Once this is realized, the hypothesis that the plane suffered an accident that left it flying on autopilot becomes rather less likely than the plane being deliberately directed towards a part of the southern ocean where presumably whoever was in charge believed the aircraft would never be found.

Indeed the NTSB tracks appear to implicitly assume an absolute not a magnetic heading, so would require the plane to be flying in a pre-programmed direction. Of course we need to see the ping arcs themselves (or at least get absolute confirmation about the trend in the ping arcs) before reaching a definitive conclusion, but this issue appears quite significant for any assessment of what might have happened onboard MH370.

Agreed, however, for the families, surely they have a right to know what happened to their loved ones, can completely understand their frustration must be an awful time, nothing worse than not knowing makes it hard to grieve properly without an explanation I know i've been there.

Could the sealed evidence be that ME's have the plane and passengers? Hence 'sealed'. The word suggests that Malaysia may have been ordered to seal the details ---> by US??

Like I have said for 300 pages - fishier than fish in the IO!

SEALED?!?!?! SEALED?!?!?!?!!!! O hell no!!! Are you kidding me?! Nonono....these families need answers! This is unacceptable! Wonder what exactly was in the cargo????? This is the last piece of news I expected! Surprised, not exactly, but they can't do this to the families....

Sealed?

Hmmm..... early on the didn't the Malaysian government say this was a threat to their national security?

If you add the two together it implies they've known from the get-go what was up.

Do you have a source for that?

Back to debris, this was posted on pprune and twitter, the census of opinion is that its a window from the 777.

Just un earhed abit more info that may be of interest -

I assumed the Hex code(plane identity) that is broadcast through the transponder, was not easily changed and at best would require an experienced team of avionics specialists? Apparently Not, the hex code can and apparently is changed even in the cockpit by the crews.

So this adds another factor to things and posts the question - was MH370 flight information changed delibratly in the cockpit, could it then have re-appeared as a different flight number and hex code?

Interesting.

I guess the relevant question in this case would be, what identifier was inmarsat using to determine the location along the southerly arc? Is it some identifier independent of the transponder hex code? If so, changing the hex code wouldn't fool inmarsat.

Thanks for this info UK. This is news to me, we always took ours to the avionics techs. Could you provide a source for this so I can educate myself? Cheers

ok,, enough crap,,,why is it no one else thinks of this but me it seems?????


"Malaysia Airlines did have an incident in August 2005 with a 777 flying from Perth to Kuala Lumpur in Malaysia. While flying 11,580 metres above the Indian Ocean, the plane’s software incorrectly measured speed and acceleration, causing the plane to suddenly shoot up 915 metres. The pilot disengaged the autopilot and descended and landed safely back in Perth. A software update was quickly made on planes around the world."




HELLO,,,

For instance,,,,,,"The Crypto Locker virus is considered to be a historically devastating virus because it holds your computer hostage until you pay a ransom."



its even called "computer virus hijack"



hello,,,,every hijacker was mentioned,,,EXCEPT ONE.


a computer software hijacker.


case closed.

Because you can't hack a commercial plane. Even if you could the pilots can override the computer, or reboot it, and at that point they're back in control of the plane.

Here is what US pilots are expected to do for lost Comms. FAA Lost Comms Procedures

Thank you for the link. Interesting stuff on this site.

One of the procedures stated the a failed communication or radar would probably be considered an emergency and a search and rescue conducted.

I've noticed a reoccurring theme to your posts. You seemed to think if tech isn't acknowledge by PUBLIC release, it's IMPOSSIBLE.

Not true.....

Of course there's stuff which is kept secret. As for hacking, plenty of things have been hacked into that were thought to be secure. Goodness, on a daily basis hackers find ways to circumvent security.

I am quite aware of black projects. I have a lot more information on them than the average person. Person A hacks the airplane. Pilot B, notices that the plane is not doing what it's supposed to do. Pilot C goes to the circuit breaker panel and pulls the flight computer circuit breaker. Person A is now locked out of the computer, because it's powered down. Oh look. Hack resolved. It's that simple.

But hell, what do I know about planes. I only spent the first 3/4ths of my life around them working on them. I guess I really don't know crap about it.

here,, catchup,,,,,or is it ketch up?

"The Digital Fly-By-Wire (DFBW) program, flown from 1972 to 1985, proved that an electronic flight control system, teamed with a digital computer, could successfully replace mechanical control systems. Electric wires are the linkage between the cockpit and control surfaces on a DFBW aircraft. Command signals from the cockpit are processed by the digital flight control computer and transmitted to actuators that move control surfaces correspondingly.

Nearly every new military and commercial aircraft in the world, from high performance fighters to jetliners circling the world - and NASA's fleet of space shuttles - incorporate DFBW flight control systems."


ohhh yelling and being rude is fine ,,cause dont give a #

reply to post by BobAthome


I'm well aware of fly by wire and how it works. That doesn't change the fact that the computer that controls is can be rebooted, or even powered off. Then your hacker gets nowhere, because there's no computer to hack.

edit on 3/27/2014 by Zaphod58 because: (no reason given)

What about the Boeing Anti-Terrorism Auto-Land System? That would be something that would be kept secret. It may not be on military aircraft, so you may not be aware of it. This is probably why Malaysia is sealing the ATC transcripts.

“There is a need in the industry for a technique that conclusively prevents unauthorised persons for gaining access to the controls of the vehicle and therefore threatening the safety of the passengers onboard the vehicle, and/or other people in the path of travel of the vehicle, thereby decreasing the amount of destruction individuals onboard the vehicle would be capable of causing,” the patent authors write. “In particular, there is a need for a technique that ensures the continuation of the desired path of travel of a vehicle by removing any type of human decision process that may be influenced by the circumstances of the situation, including threats or further violence onboard the vehicle.”
