How MH370 was found

from Bangkok Post

LONDON - The satellite operator Inmarsat said Monday it managed to work out which direction the missing Malaysia Airlines plane flew in by measuring the Doppler effect of hourly 'pings' from the aircraft.

Malaysia's prime minister announced earlier that the Inmarsat analysis of flight MH370's path placed its last position in remote waters off Australia's west coast, meaning it can only have run out of fuel above the southern Indian Ocean.

Inmarsat explained how they plotted models of the flight's route by measuring the Doppler effect of satellite pings, giving corridors arcing north and south along which the plane could have flown for at least five hours.

Despite the plane's communication systems being switched off, satellite pings were still bouncing back from the aircraft, which which vanished on March 8 with 239 people on board while flying from Kuala Lumpur to Beijing.

The pings are sent from a ground station to a satellite, then onto the plane, which automatically sends a ping back to the satellite and down to the ground station.

They do not include global positioning system (GPS) data, time or distance information.

So the British satellite operator measured the amount of time it took for the pings to be returned.

"We looked at the Doppler effect, which is the change in frequency due to the movement of a satellite in its orbit," Chris McLaughlin, Inmarsat's senior vice president of external affairs, told Britain's Sky News television.

"What that then gave us was a predicted path for the northerly route and a predicted path the southerly route."

"We don't know whether the plane stayed at a constant speed; we don't know whether its headings changed subsequently," he explained.

Therefore, "we applied the autopilot speeds -- about 350 knots. We applied what we knew about the fuel and range of the aircraft to hit the series of ping information we had.

"Normally you'd want to triangulate, often you'd have GPS. But because aircraft in that region are not mandated to send out signals of their location we were working from blind, so this is very much a unique approach, the first time it's been done."

They then compared those figures to data from other Malaysia Airlines planes and similar flight routes, which definitively showed the plane could only have been going down the southern corridor, and would eventually have run out of fuel.

They established an "extraordinary matching" between Inmarsat's predicted southern path and readings from other planes on such routes.

The BBC reported that as far as could could be worked out, the plane was flying at a cruising height, above 30,000 feet (9,100 metres). They found no evidence of fluctuating heights.

Inmarsat handed over new information to Britain's Air Accidents Investigation Branch on Sunday for checking.

"By yesterday they were able to definitively say that the plane had undoubtedly taken the southern route," said McLaughlin.

He called for all commercial aircraft to be fitted with existing technology that would mean a plane cannot go missing.

Ethics in C&P

When posting/sharing something on your wall, something that is not an original work of yours, it would be great if you could put the credit as part of the first paragraph. As we all know most people don't bother to read past a few paragraphs, what's more all the way to the end where you usually put the credit, if you bothered to. I know you mean well, and the article you shared are brilliantly worthy, but please give credit where it's due, right at the top and not buried deep eleven scrolls down.

And to those passing off works of others as their very own, you are only as original as what you share. We know that you don't suddenly develop great writing skill overnight, so please spare yourself from public shaming, give credit where it's due. People will at least compliment you for your great choice of read.

Backspace

I was about to respond to you, everything was all typed, everything I always wanted to say but never had the courage to, my thoughts has finally been translated into words. For you. 

All that I need to do was to hit 'enter', but my finger found the 'backspace' key instead and I started clicking. And clicking. Until all has been erased. Like I never wrote it, like I never gave it the slightest thought.

Sometimes silence is the best way to go. I just wish you know that, and not think it's a sign of weakness or submission. Sometimes you got to appear weaker in order to be the bigger person. I just wonder where's  the backspace key to the thoughts in my mind, because there's a lot that need erasing.

MH370 : Maybe the answer has been staring at us all these while

 

We, non-stakeholders are on a need to know basis. Some information which are deemed to be too sensitive will never be released, that we got to accept. 

We need to read and listen properly, think of who (or their assets) has been going out of their way to give misleading information, out to make Malaysia look bad in every sense? Who has been pointing in one direction and adamant that's the right one. Who always seem to be policing the world, knowing every nook and crannies of the deepest cave, eyes trained on every spot on earth, yet now keeping mum, funnily none of the so called respectable media's are calling them out. 

As much as love our nation, I don't believe we are capable of such cover up, so who do you think is responsible for either the whole thing or its cover up. I understand withholding information pending investigation, but eventually the ought to be some conclusion, I don't mind waiting. 

The most important thing right now is to find the aircraft with all the passengers and crew alive and safe.

Occam's Razor perhaps? #mh370 #prayformh370
