There have been numerous spottings of debris and "slicks" which have turned out to be something other than what is being searched for.

Is this area of ocean relatively littered with debris?

If so, and if the aircraft left little in the way of large floating pieces (this includes any option of the aircraft being outside the search area), then rather than looking for a needle in a haystack, the searchers might be trying to find a needle in a field of other needles.
One of the relatively few intelligent comments on this thread!

Yes I think this is one of the main reasons why this search didn't yield quick results

If this turns out to be terrorist-related, (still a big 'if' at this stage), those who are opining that the terrorists are 'breaking the usual rules' by not claiming responsibility probably should remember that the terrorists 'broke the usual rules' on Sept 11th 2001. Anyone old enough to have been in Aviation pre-Sept 2001 will recall the "don't resist, co-operate in every possible way" rules that were universal in every airline (with the possible exception of El Al and Korean Airlines) until the events of that Tuesday changed everything.

If this is terror-related, maintaining silence is proving remarkably effective, particularly while the wreckage remains not located. The mainstream media will eventually lose interest if nothing happens soon - (it would probably be a very different situation if 230 Americans had been involved, but let's not go there) - but the SAR effort will continue, downgraded, but in some form - and a considerable expense - until something is found. And then the real expense will start, particularly if a deep water recovery is involved.

Someone's said it before me - this could end end up costing a lot of governments and as many airlines huge amounts of money. Which means it will end up costing us, the travelling public, huge amounts of money as well.

If terrorists are involved, the aircraft - or more likely its wreck site - could be many thousands of miles away from the current search area.

Example of crew incapacitation in case of a fire
 
For our guest forum viewers, just to give an example of how quickly the situation can overcome a flight crew in case of a fire. (I do not directly speculate / cross-reference to this report in connection with flight MH370)

@keypilot


FACT: contrary to what has been reported by some here, AF447 wreckage was found only after 5 days, and was near to the last known position; thus, we are now currently still inside the timeframe for this accident, and the amount of time taken to find MH370 cannot be considered to be "unprecedented" or otherwise exceptional
Actually not a fact. The wreckage was spotted after TWO days but it took another 3 days to get vessels to the scene.


But if someone suggested 4 days after AF447 had disappeared, that it stalled at cruise altitude and was maintained in a stalled state by intentional control input until impact with the sea, this would have been dismissed as ludicrous.
That very scenario was correctly identified on this very Board.

As a pilot, I *think* we can discard a couple of theories suggested recently:

1. "Urgent", but not instantaneously critical situation, eventually leading to crash. If the aircraft had some kind of failure that eventually led to the aircraft descending and crashing, the pilots would have almost certainly made a mayday call. The first duty of any pilot is to deal with the situation at hand, "aviate", but once it is clear that the situation is serious, almost any professional pilot is going to take a few seconds to make a radio call in the blind. That is ingrained in training. We just do it. We've all had to do it at one stage or another coming up through our training. It's almost automatic and it doesn't stop you diagnosing the problem and taking action. Unless it is so bad that the plane is literally falling apart or you genuinely have lost all radio contact without notice, which would be highly unusual.

2. "Hypoxia". Once on autopilot, which the aircraft would have been in cruise at FL350, even an explosive depressurization would have left the plane in cruise all the way to Vietnam, at which point the transponder would have started responding to radar pings. And of course, worst case, the plane keeps cruising and runs out of fuel way up in mainland China. It's not just going to disappear.

Four search days have gone and there's no trace along the route of flight. An enormous aircraft. 12 year old 777 in calm weather from a carrier with a good safety record. I can't think of any more likely scenario, than, as much as I hate to suggest it, but it all points to...an instantanous catastrophic event, e.g. bomb.

All things considered and in the absence of any information, am I alone in thinking that this the most likely cause?

There is, on average, a handful every decade. Fortunately, almost all are prevented:

https://en.wikipedia.org/wiki/Timeli...ombing_attacks

When most people think of an airline bomb attack, I'd say they'd think of Lockerbie in 1988. Probably because it was Pan Am and a 747. But there's been a few since then.

I just can't think of a more likely scenario at this stage, however unfortunate. 777's have an exceptional track record.

I'm a SLF living in Malaysia with a brother who is a pilot with another airline in Malaysia.

I'm not certain if anyone has seen this piece of news yet about the search in the Straits of Malacca. thhttp://www.malaysiakini.com/news/256723

The source is Malaysiakini which is viewable on paid subscription. I've cut and pasted the article here ( I hope that is ok mods)


The search for Malaysian Airlines MH307 plane has been expanded to Sumatran waters, north of Straits of Malacca, as military radar may have detected the missing plane in the vicinity of Pulau Perak.

A Berita Harian report today quoted the Royal Malaysian Air Force (RMAF) as saying the plane may have reversed course further than expected while on its way from Kuala Lumpur to Beijing.

Air Force chief Rodzali Daud (left) is quoted as saying that based on military radar readings from its station in Butterworth, MH370 may have turned west after Kota Bahru and flew past the east coast and Kedah.

"The last time the plane was detected was near Pulau Perak, in the Straits of Malacca, at 2.40am," Berita Harian quotes Rodzali as saying.

This contradicts with earlier reports that the aircraft had disappeared from radar screens 120 nautical miles off Kota Bharu and over the South China Sea, at 1.30am on March 8.

The Department of Civil Aviation (DCA) had previously said the search for the Boeing 777-200ER aircraft, which is missing for the fourth day, had previously been focused around the waters between East Malaysia and Vietnam.

Berita Harian also said that military radar noted that the plane was flying about 1,000 metres lower than its original altitude of 10,000 metres after the about turn.

There are 227 passengers, including two infants, and 12 crew members on board the plane. Of these, 152 are Chinese nationals, 38 are Malaysians and the rest are from 12 other countries.

Meanwhile, Utusan Malaysia reported that 20,000 fishermen nationwide have been roped in to help in the search-and-rescue operation.

The newspaper quoted Agriculture and Agro-based Industries Minister Ismail Sabri Yaakob as saying that this would involve 1,788 fishing boats around the waters off Kelantan, Terengganu, Perlis, Perak and Penang.

The fishermen were roped in at the request of acting Transport Minister Hishammuddin Hussein, Ismail said.

Hi,

Keypilot

Indeed if the time taken for find MH370 go not over almost 2 years :} (time to find AF447) it will not be "unprecedented"

Keeping perspective
 
Trying to keep some perspective...

Just for the search on the East side of Pensinsular Malaysia, at the quoted 100km radius search range from IGARI, spotting a seat cushion is the rough equivalent of spotting a grain of caster sugar in Central Park.

MH seats are often blue (not always - I have no idea for this a/c), so consider the sugar in Central Park might be colored green or brown to get this in some perspective of what the SAR guys are looking for.

Even assuming there are a couple of hundred seat cushions and similar size debris, that's a spilled packet of sugar in Central Park, and quite spread out after a couple of days of drifting.

The Press briefing is becoming a farce.

Stop giggling and laughing!

an instantanous catastrophic event, e.g. bomb.
The only problem with this theory (or any 'explosion') is that it spreads a lot of debris, more floating debris the higher the altitude. Unless they search in wrong places - no debris so far.

I made this exact mistake. This is not quite accurate; while some sort of debris were located shortly after the accident, their attribution to AF447 was later retracted, and first pieces confidently identified as belonging to AF447 were only found 5 days after the accident.

However, the key difference between AF447 and MH370 is that AF447 went down completely off the radar. People searching for AF447 had a huge area, ~400 nm in diameter, to work with, and there were lots of pieces of unrelated rubble within this area. The initial search for MH370 was based on the assumption that the aircraft (or a large part of it) disintegrated at the moment when all transmissions from both transponders ceased. If this were the case, we would've found some debris, the lesson of AF447 notwithstanding. If MH370 went down in a two-phase event, with the transponder and the ADS-B transmitter shut down a one point and the aircraft disintegrating at some different point, the debris could be almost anywhere.

Maybe I am being a little naive here, but.....

Why are Commercial Airliners not fitted with SLBs (Sonic Locator Beacons)?

Would this not make SAR Ops of this type easier at a relatively low price....

The police IG at the presser live at the moment (0715) says the known Iranian lad with the stolen passport (and his buddy) were most likely asylum seekers, not terrorists. When he didn't show up at FRA, mom called the authorities.

Frenchwalker 11th Mar 2014 07:26

It was already stated this morning that the two Iranians were trying to get to Europe via china and that they have been identified

Agreed.

Very unprofessional and even sarcasm from the police minister / commander.

Ollie Onion 11th Mar 2014 07:29

Several news sites now carrying reports about several different fisherman reporting a 'low flying' aircraft moving very fast just off the Malay coast. One fisherman saying that the lights were about the 'size of coconuts' which is why he knew it was very low. Apparently these reports are why the search area has now been expanded to include areas of land.

It would appear that they really have no idea what general area this aircraft went down in.

If indeed this was the aircraft flying low back towards Malaysia then it must be a deliberate act to turn around, descend and then crash the aircraft...... of course these reports could be completely false as eye witnesses are historically very very bad sources when it comes to aircraft accidents.

Since they are looking west of Malaysia I suspect they have ACARS data. But why is it kept so secret, or don't have any data, is a mystery.

Malaysian officials non-committal on MH370 ACARS transmissions - 3/11/2014 - Flight Global


.... acting transport minister Hishamuddin Hussein, he instead embarked on one of the search and rescue flights looking for the aircraft in the Straits of Malacca on Malaysia’s west coast.

Media reports have said that no ACARS data was received from the aircraft when its transponder disappeared from radar ....

... "All Malaysia Airlines aircraft are equipped with continuous data monitoring system called ACARS which transmits data automatically," says MAS. "Nevertheless, there were no distress calls and no information was relayed."

Presumably the aircraft would have transmitted ACARS data prior to its disappearance, but an industry source familiar with ACARS says this would be entirely dependent on the level of service ...

ACARS is "broadcast" and unencrypted, anyone can receive and decode the messages.

VR-HFX 11th Mar 2014 07:43

Quite some number of pages back I made a post that has disappeared as completely as MH370.

The initial press release from MH stated clearly that the a/c lost contact with Subang ATC at 0240 local time. This was also posted on page 1 of this thread. It has not been redacted to the best of my knowledge.

The transponder supposedly stopped at 0121 local. One hour and twenty minutes creates a rather large search area from the point at which the transponder ceased transmitting.

Clearly something is known that has not been shared yet.

gulab100 11th Mar 2014 07:44

Wrong direction?
 
Is it possible that the entire flight from KL was on the wrong heading? is this the reason why the search in Mallacca Strait?

No offense intended.
