Malaysia Airlines Flight 370 is Missing

Underwater locator beacon

An underwater locator beacon (ULB) or underwater acoustic beacon is a device fitted to aviation flight recorders such as the cockpit voice recorder (CVR) and flight data recorder (FDR). ULBs are also sometimes required to be attached directly to an aircraft fuselage. ULBs are triggered by water immersion; most emit an ultrasonic pulse of 37.5 kHz at an interval of once per second.

This is the place where it's found. Now according to reporters on board Haixun01, it is almost confirmed that they have found the black box.

Coincidentally (or is it?), today is China's traditional Qingming festival, a day we the Chinese people pay our tribute and respect to those who died. If we really found what we thought we have found, then maybe, this is the best way to pay our tribute to those 154 Chinese on board MH370.

Nonetheless, the job hasn't been done and there's still a long way to go, to confirm whether it's really the black box, to recover it, analyse the data, find out why, and search for any remains of the passengers on the plane.

Edit 1: So new information showed that Haixun 01 in fact first detected the signal yesterday. But to confirm, they went there again and detected the same signal again. Precise location is 25.58°S ,101.26°E.

Edit2: According to Haixun 01, after comparing with the sample signal sent by Boeing, they can confirm that the signal they have detected is the same as the sample

PERTH, Australia (AP) — China's official news agency says a Chinese ship that is part of the multinational search effort looking for the missing Malaysia Airlines plane has detected a "pulse signal" in southern Indian Ocean waters.

The report says a black box detector deployed by the vessel, Haixun 01, picked up a signal at 37.5Hz per second Saturday at around 25 degrees south latitude and 101 degrees east longitude.

The report said it was not established whether that the signal was related to the missing jet.

The Australian government agency coordinating the search would not immediately comment on the report.

Okay I was too excited just now. We'll still need to wait for official confirmation on this and until the black box is recovered anything is possible.

Let's just wait and see

Re: Malaysia Airlines Plane is Missing

I have yet to see conspiracy theories that incorporate the satellite pings. That would immensely complicate the plot that have to bring in the satellite company and maybe some countries.
That's easy. You need to disable the pingers on the aircraft at the right time and have an alternative pinger sending pings at exactly the right time and at exactly the right frequency and strength to represent the path you want investigators to believe the aircraft followed. Any developed country as well as some large companies and perhaps a few terrorist organisations should be able to do this. Take a good place for your pinger and don't forget to account for the exact distance to the satellite. If Diego Garcia is part of your theory place the pinger there. Otherwise put it on a ship in a rather empty part of the Indian Ocean.

looking at the pictures from that link, it appears Haixun 01 is using commercial pinger receiver deployed from its boats. There are three persons wearing headphones in the boat, in agreement with the news report that three crews heard the pulse signal.

the equipment looks similar to this.

It is not very sophisticated equipment compare to the American TPL-25. One would expect the detection range to be much shorter, and it can't change depth. It would a huge stroke of luck if Haixun 01 find the black boxes. But the crew of Haixun 01 appears to have been using this equipment since the beginning of the search, unlike the American locator which is just been deployed.

this appears to be the model of receiver used by Haixun 01's boat.

I hope it's not overly zealous Chinese media reporting anything that crosses them without confirmation.

Theory two. If I was the PRC government And I just bought something that was stolen from the Americans and I decided to ship it on a civilian flight I would have agents on the flight. Second part of this plan what in pray tell was supposed to happen to the flight crew and passengers at Diego Garcia? And when they got to China? I mean the Chinese would find out that the US pull this stunt real quick. Unless Of course the passengers all died, then what happened to the Israeli and American mission impossible team? Did they die to? And If MAS370 did land at Diego Garcia how in the be of hell did the US keep it under wraps? There have to be thousands of people on that base American navy and Air force. The bigger the conspiracy the less a secret. Did the US simply swear them all to secrecy? Really thousands of people who could have seen a civilian jet not just land but also take off... On a base that the PRC watches like a pervert does his hot neighbor who leaves the blinds open.
And finally, American Drones are operated via satcom from locations far away from the battlefield, unless the Taliban was raiding Bahgram or its doubtful they would have gotten any thing that critical to the USA Drone program unless it was the Drone itself in which case as Mace said why did the US not hellfire it into a fine powder? And even the historical grounding was bull the F117 was downed as a stroke of luck. The flight planers got complacent and kept reusing the same flight path. Eventually someone figured it out and parked a missile launcher there. The missile shot at the Chinese embassy is a favorite of conspiracy theories, but even the best of equipment can fail.
Theory two is frankly a 9/11 Theory rewrite.

Playing devils advocate for a moment.

If this was a government agency level covert operation, the agents need not suicide themselves. They could easily pack parachutes in their main luggage, or even have parachutes in the freight cargo. Once the agents killed everyone and got what they needed, they could access the cargo deck via crew elevators, unpack their chutes and communications gear, radio in, perform a halo jump and get picked up by a waiting SSN.

The claim also was that the drone controllers got nabbed during transit, when the Taliban hit a convoy, so that's unlikely but perfectly possible.

Where that theory falls on its face is explaining just why it was necessary to get the drone controllers to Malaysia, and how the Taliban managed that, when it would have probably been easier and safer to get the equipment directly to China via the shared land boarder, or even through Pakistan.

If it was a government op, it was either planned that all passengers had to die, or something went catastrophically wrong.

For the first scenario, it is really hard to think of anything valuable enough for any government to seriously consider, never mind sanction, such high profile mass murder. This isn't taking a bunch of guys few would miss behind a shed and hoping no one would notice or care. The world, or at least the Chinese, would not rest until they got answers. The consequences of discovery would be too catastrophic to risk no matter what was at stake or how small the chance of damning evidence being found.

As such, I am leaning more towards covert mission gone horribly wrong. The scenario that springs most readily to mind would be a similar case to the infamous Moscow Theatre seige.

The plan was for the pilot to shake the plane about a bit, and then deploy masks instructing the crew and passengers to use them. No one would have thought to disobey such an order. Only instead of just air, the masks' supply were laced with sleeping gas (or they could have just released the gas directly through the plane's ventilation system. With it being a red eye, few would have been suspicious if they woke up all of a sudden without realising that they had fallen asleep).

The idea was to knock everyone out long enough for the agents to do what they needed to do. Then the pilot turns off the sleeping gas and everyone wakes up in Beijing none the wiser, with their mark and escort having no idea what happened to the package.

Problem was someone messed up the dosage and the gas ended up killing everyone.

Agents, and their handlers back at HQ freaked out when they realised what happened, that's when they disabled the transponders and started to actively try to evade radar by dropping to the deck. The many course corrections could be explained by the chaos of everyone trying to come to grips with the disaster and the agents getting contradictory orders as people higher and higher up the chain found out and everyone wanted it handled differently.

Ultimately the decision was to fly the plane as far off course as possible and ditch it in the hope that no one ever finds it, or at least no one can find the crash site in time to gather any incriminating evidence, like bodies filled with lethal concentrations of sleeping gas for example.
