Tuesday, March 25, 12:30 AM GMT +0800 Malaysia Airlines MH370 Flight Incident - Media Statement 24

It is with deep sadness that Malaysia Airlines earlier this evening had to confirm to the families of those on board Flight MH370 that it must now be assumed the flight had been lost. As the Prime Minister said, respect for the families is essential at this difficult time. And it is in that spirit that we informed the majority of the families in advance of the Prime Minister’s statement in person and by telephone. SMSs were used only as an additional means of communicating with the families. Those families have been at the heart of every action the company has taken since the flight disappeared on 8th March and they will continue to be so. When Malaysia Airlines receives approval from the investigating authorities, arrangements will be made to bring the families to the recovery area and until that time, we will continue to support the ongoing investigation.

怀着沉重的悲伤之情,马来西亚航空公司今晚早些时候向MH370失联航班乘客及机组成员的亲属确定了飞机失事这一推断。 正如马来西亚总理纳吉布.扎克拉之前在媒体声明中所说的,在这一艰难时刻,对各位乘客家属的尊重至关重要,也正是因为这一原因,我们在总理发表媒体声明之前,通过电话事先通知了大部分家属这一消息,同时我们还使用短信作为额外的方式与家属进行了沟通。自从3月8日飞机失联以来,乘客家属一直都是我们每一步行动的重中之重,在日后的工作中我们也将继续如此。一旦从调查机关获得批准,马来西亚航空公司便会安排将各位乘客亲属带往恢复区,其后再继续参与到正在进行的调查中去。

Tuesday, March 25, 12:30 PM MYT +0800 Malaysia Airlines MH370 Flight Incident - Media Statement 25

By: Tan Sri Md Nor Md Yusof, Chairman of Malaysia Airlines

As you will be aware, last night the Prime Minister of Malaysia, Dato' Seri Najib Tun Razak, announced new evidence regarding the disappearance of MH370 on 8th March.

Based on this evidence, the Prime Minister’s message was that we must accept the painful reality that the aircraft is now lost and that none of the passengers or crew on board survived.

This is a sad and tragic day for all of us at Malaysia Airlines. While not entirely unexpected after an intensive multi-national search across a 2.24 million square mile area, this news is clearly devastating for the families of those on board. They have waited for over two weeks for even the smallest hope of positive news about their loved ones.

This has been an unprecedented event requiring an unprecedented response. The investigation still underway may yet prove to be even longer and more complex than it has been since March 8th. But we will continue to support the families – as we have done throughout. And to support the authorities as the search for definitive answers continues. I will now ask our Group Chief Executive¸ Ahmad Jauhari Yahya, to provide you will with fuller details of our support for the families.

By: Ahmad Jauhari Yahya, Group Chief Executive Officer, Malaysia Airlines

I stand before you today not only as the Group Chief Executive Officer of Malaysia Airlines, but also as a parent, as a brother, as a son. My heart breaks to think of the unimaginable pain suffered by all the families. There are no words which can ease that pain. Everyone in the Malaysia Airlines family is praying for the 239 souls on MH370 and for their loved ones on this dark day. We extend our prayers and sincere condolences.

We all feel enormous sorrow and pain. Sorrow that all those who boarded Flight MH370 on Saturday 8th March, will not see their families again. And that those families will now have to live on without those they love.  It must be remembered too that 13 of our own colleagues and fellow Malaysians were also on board. 

And let me be very clear on the events of yesterday evening. Our sole and only motivation last night was to ensure that in the incredibly short amount of time available to us, the families heard the tragic news before the world did. Wherever humanly possible, we did so in person with the families or by telephone, using SMS only as an additional means of ensuring fully that the nearly 1,000 family members heard the news from us and not from the media.

Ever since the disappearance of Flight MH370 Malaysia Airlines’ focus has been to comfort and support the families of those involved and support the multi-national search effort. We will continue to do this, while we also continue to support the work of the investigating authorities in the Southern Indian Ocean.

Like everyone else, we are waiting for news from those authorities. We know that while there have been an increasing number of apparent leads, definitive identification of any piece of debris is still missing. It is impossible to predict how long this will take. But after 17 days, the announcement made last night and shared with the families is the reality which we must now accept. When Malaysia Airlines receives approval from the investigating authorities, arrangements will be made to bring the families to the recovery areas if they so wish. Until that time, we will continue to support the ongoing investigation. And may I express my thanks to the Government and all of those involved in this truly global search effort.

In the meantime, Malaysia Airlines’ overwhelming focus will be the same as it has been from the outset – to provide the families with a comprehensive support programme. Through a network of over 700 dedicated caregivers, the loved ones of those on board have been provided with two dedicated caregivers for each family, providing care, support and counsel. We are now supporting over 900 people under this programme and in the last 72 hours, we have trained an additional 40 caregivers to ensure the families have access to round-the-clock support.

In addition, hotel accommodation for up to five family members per passenger, transportation, meals and others expenses have been provided since 8th March and that will continue.

Malaysia Airlines has already provided initial financial assistance of USD 5,000 per passenger to the next of kin. We recognize that financial support is not the only consideration. But the prolonged search is naturally placing financial strain on the relatives. We are therefore preparing to offer additional payments as the search continues.

This unprecedented event in aviation history has made the past 18 days the greatest challenge to face our entire team at Malaysia Airlines. I have been humbled by the hard work, dedication, heartfelt messages of concern and offers of support from our remarkable team. We do not know why, and we do not know how this terrible tragedy happened. But as the Malaysia Airlines family, we are all praying for the passengers and crew of Flight MH370.

马航MH370事件 媒体声明25


















今天我站在大家面前,不仅是作为马来西亚航空公司集团首席执行官,同时也作为一个父亲,一个兄长、和一个儿子。一想到所有家属所遭受的令人无法想象的伤痛,我的心也无比沉痛。没有什么话语能抚平伤痛。在这不幸的一天,马航的每个人都在为MH370航班上的239 个在天之灵以及他们挚爱的亲属而祈祷。我们表达最真挚的祈祷和哀悼。














马来西亚航空公司已经为每一位乘客的直系亲属提供了5,000 美元的初始补助金。我们知道资金援助并不是唯一的因素,但持久的搜救工作对失联乘客家属而言无疑将造成一定的经济负担。因此随着搜救的持续进行,我们也会为家属继续提供资金援助。

Tuesday, March 25, 06:50 PM MYT +0800 Malaysia Airlines MH370 Flight Incident - Press Briefing by Hishammuddin Hussein, Minister of Defence and Acting Minister of Transport

Introductory statement

As the search for MH370 continues, we remain focused on narrowing the search area.

With such strong co-operation from our international partners, the challenge is no longer diplomatic. It is now primarily technical and logistical. Because the scale of the investigation is now much more complex, the release of technical and logistical information will be handled differently. As you have seen today, this means that Malaysia Airlines will take the lead in communicating with the families.

As the search area has narrowed, new challenges have arisen, including managing resources in a remote search and rescue effort. We continue to work closely with our friends and partners as we seek to marshal more specific resources in support of the operations in that area.

1. New data

Last night the Prime Minister announced that according to new analysis of satellite data, Inmarsat and UK Air Accidents Investigation Branch (AAIB) have concluded that flight MH370 ended in the southern Indian Ocean.

Today I will provide further details of how the data was analysed, as provided to us the UK AAIB. This information is quite technical in nature. So although I will give you as much information as I can, I will not be in a position to answer questions about this data analysis today.

However, we will accept written questions which will be answered as soon as possible. We will be providing this information as a press release at the end of this press conference. This is the information provided to us by the AAIB. Click <a href="" target="_blank">here</a> for the document.

2. Further details

In recent days Inmarsat developed a second innovative technique which considers the velocity of the aircraft relative to the satellite. Depending on this relative movement, the frequency received and transmitted will differ from its normal value, in much the same way that the sound of a passing car changes as it approaches and passes by. This is called the Doppler effect. Click <a href="" target="_blank">here</a> for Doppler document.

The Inmarsat technique analyses the difference between the frequency that the ground station expects to receive and that actually measured. This difference is the result of the Doppler effect and is known as the Burst Frequency Offset.

The Burst Frequency Offset changes depending on the location of the aircraft on an arc of possible positions, its direction of travel, and its speed. In order to establish confidence in its theory, Inmarsat checked its predictions using information obtained from six other B777 aircraft flying on the same day in various directions. There was good agreement.

While on the ground at Kuala Lumpur airport, and during the early stage of the flight, MH370 transmitted several messages. At this stage the location of the aircraft and the satellite were known, so it was possible to calculate system characteristics for the aircraft, satellite, and ground station.

During the flight the ground station logged the transmitted and received pulse frequencies at each handshake. Knowing the system characteristics and position of the satellite it was possible, considering aircraft performance, to determine where on each arc the calculated burst frequency offset fit best.

The analysis showed poor correlation with the Northern corridor, but good correlation with the Southern corridor, and depending on the ground speed of the aircraft it was then possible to estimate positions at 0011 UTC, at which the last complete handshake took place. I must emphasise that this is not the final position of the aircraft.

There is evidence of a partial handshake between the aircraft and ground station at 0019 UTC. At this time this transmission is not understood and is subject to further ongoing work. No response was received from the aircraft at 0115 UTC, when the ground earth station sent the next log on / log off message. This indicates that the aircraft was no longer logged on to the network.

Therefore, sometime between 0011 UTC and 0115 UTC the aircraft was no longer able to communicate with the ground station. This is consistent with the maximum endurance of the aircraft.

This analysis by Inmarsat forms the basis for further study to attempt to determine the final position of the aircraft. Accordingly, the Malaysian investigation has set up an international working group, comprising agencies with expertise in satellite communications and aircraft performance, to take this work forward.

3. Technical background

The new analysis I have described above was convincing enough for the AAIB to brief the Prime Minister that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth. Within a few hours, the families had been informed, and the Prime Minister announced the new development to the world.

As the Prime Minister stated, this type of analysis has never been done in an investigation of this sort. There remains more work to be done, and we are grateful to Inmarsat, AAIB and the international investigations team, who are continuing to work with the Malaysian authorities. This is a developing situation, and as soon as we know more, we will share it.

4. Operational update

As a result of this new data analysis, the search and rescue operation in the northern corridor has been called off. We have also stopped the search and rescue operation in the northern part of the southern corridor, close to Indonesia.

All search efforts are now focused in the southern part of the southern corridor, in an area covering some 469,407 square nautical miles, as against the 2.24 million square nautical miles which we announced on 18th March.

We are currently working to further narrow down the search area, using the four methods I mentioned previously: gathering information from satellite surveillance, analysis of surveillance radar data, increasing air and surface assets, and increasing the number of technical and subject matter experts.

On the assets deployed, 2 Korean aircraft left Subang airport for Perth this morning, to help in the multinational search operation. No flights from Perth to the search area took place today, due to bad weather. 6 Chinese ships are currently in the search area. They are expected to arrive within the vicinity of MH370’s last known position by tomorrow morning. These ships include the ice breaker ‘Xue Long’.

HMAS Success is also currently in the search area.

The American Towed Pinger Locater – an instrument that can help find a black box - is currently en route to Perth and will arrive tomorrow. The system will be fitted onto the Australian ship Ocean Shield, which is due to dock in Perth on 28th March. The Ocean Shield, fitted with the Towed Pinger Locater, is due to arrive in the search area on 5 April.

5. Concluding remarks

The new analysis shared with the investigation by Inmarsat and the AAIB has focused our efforts on the southern part of the southern corridor.

Although yesterday’s news was incredibly hard for the family members, as our Prime Minister said, it was released out of a commitment to openness and respect for the relatives, two principles which have guided the investigation.
