Mystery Flight MH370 missing

[Zidane98]

All planes are monitored. I just can’t find where I saw that every commercial plane’s in flight position is known at all times and it can’t be turned off by the pilot.

ACARS can be turned off, SATCOM can be disabled. At least back in 2014 that was the case. What can't be turned off is the satellite link (hourly handshake) unless its power source is shut down (left hand bus in the 777). This must have happened as disabling SATCOM normally would result in a message being sent to the airline.

Private jet that disappeared in 1971 has just been found

Mystery of private jet that vanished in 1971 is finally solved

A private jet that vanished in 1971 has been found 53 years on. The story has a tragic ending. But families of the five men on board say they're glad to finally have closure.

www.dailymail.co.uk

The aircraft was known to have crashed somewhere in Lake Champlain. See map below:



So despite the general location of the crashed aircraft being known and the area miniscule compared to the potential MH370 search area it took 50 + years to finally locate the aircraft after many searches. And we're talking depths here of 20m on average, not 4-5000m like in the Southern Indian Ocean.


Just goes to show just how difficult the MH370 search is. It crashed somewhere within 100nm of the last ping arc at 00:19 in the Southern Indian Ocean. A huge area.

What's interesting in this case is the aircraft was found in areas already searched by further examination of sonar images from a 1997 survey with advanced equipment.

This could be a possibility in the MH370 search.

I urge anyone who maintains an interest in this to read/listen to Larry Vance's book MH370: Mystery Solved.


The general consensus amongst investigators is the partial handshake at 00:19 was the SATCOM link rebooting after the APU started up following fuel exhaustion.

Vance though points out a pilot looking to deliberately ditch the aircraft may have decided to start up the APU prior to fuel exhaustion so there was no issues with losing hydraulic power to control surfaces. In this instance the aircraft could have gone on to fly significantly past the 00:19 last handshake time.

Assuming a pilot that wants to go as far south as possible this could mean even 5 minutes of flight at typical speeds of 300knots could mean flying much further south with a glide aswell. The aircraft could be up to 200km south of the 00:19 ping. His suggestion seems to be to search everywhere from 50kms past the last ping heading south which is a massive, massive search area.

KUALA LUMPUR: Putrajaya may consider Ocean Infinity’s proposal on a new search location for the ill-fated MH370 flight, says Anthony Loke.

“The new search location that was proposed by the Ocean Infinity company is based on information and latest data analysis by experts and researchers that the company had referred to,” the Transport Minister said during question and answer time in the Dewan Rakyat on Tuesday(Nov 5).

Ocean Infinity’s proposal for the search operation is credible and can be considered by the Malaysian government in its capacity as the country where the flight MH370 had been registered,” he added.

Loke was responding to a question by Chong Zemin (PH-Kampar) on whether the government still intends to continue the search for the Beijing-bound flight that disappeared on March 8,2014.

Loke said the new search location is estimated to include some 15,000 square kilometres in the Indian Ocean.

This search, he added, will be on a "no find, no fee" basis.

The government will not have to make any payment to the company if it is unable to find the remnants of the flight.

Previously, Ocean Infinity had conducted searches in the Indian Ocean from 2017 until the end of 2018.

In March, the Texas-based firm claimed that it had found new scientific evidence on the last location of MH370.

Plane is located in international waters. Don't bother asking permission from Malaysia. Find it, then invoice them a finder's fee. No payment no location of wreckage.

I wonder about the 'no find no fee' bit. How much wreckage would they need to qualify? This is one of, if not the biggest piece of wreckage found so far, found in 2016 off the coast of Tanzania

Crash site will be the requirement for payment.

That might be a tough ask if the plane disintegrated on impact or something. They might find the section with the black box/flight recorder if they're extremely lucky but the ocean currents have probably spread it far and wide.

Maybe you can argue that for the first little bit, but they do seem to be being evasive about the cargo.

"MH370 An association representing the families of passengers and crew onboard Flight MH370 today questioned whether the concealment of the flight’s full cargo manifest is a conspiracy.

MH370 had disappeared without trace in March on a flight from Kuala Lumpur to Beijing with over 200 onboard.

“We urge the authorities to make a full release of all cargo carried onboard MH370, stating clearly what was in the cargo hold,” read the statement by Voice370."

Pointing out how the cargo manifest was only released on May 1, the group said the cargo manifest released was not complete even after a delay of two months.
“We only know that there was 4,566kg of mangosteens shipped by Poh Seng Kian and a consignment of lithium batteries.
“We want to know the detailed contents and quantities of cargo in each of these consolidated airway bills and a load instruction sheet to see how the cargo holds were loaded.”

221 kg of lithium batteries I believe. I don't believe enough consideration has been made to the possibility of a fire caused by these batteries. I have read in a few places that they were faulty batteries being returned to China - e.g. https://www.quora.com/I-viewed-an-article-by-a-senior-captain-who-claimed-that-Flight-370s-loss-of-transponders-and-communications-makes-perfect-sense-in-a-fire-So-what-would-a-captain-probably-do-if-he-spotted-signs-of-electrical-fire

Fire that severe only for the aircraft to fly on for another 6 hours?


Doesn't pass the sniff test.


The aircraft was definitely under manual control at least until the final turn south. Fires that severe usually results in a crash within a relatively short timeframe.

The heaviest parts of the aircraft will sink straight to the sea floor. Wreckage recovered so far does not indicate the aircraft was smashed into a million pieces either.

For comparison, read up about Swiss Air 111:

At 22:31:18 ADT (01:31:18 UTC), Flight 111 struck the ocean at an estimated speed of 345 miles per hour (555 km/h; 154 m/s; 300 kn). The impact time also coincides with seismographic recorders at Halifax and Moncton which detected a seismic event at the time. The collision with the water decelerated the aircraft with approximately 350 g, causing it to disintegrate instantly.[3]: 116  The location of the crash was identified as approximately 44°24′33″N 63°58′25″W.[9]


Much of the wreckage of this aircraft was found on the bottom of the sea at the crash site.


Clearly MH370 impact forces were nothing like this (look at the flaperon). Most of the aircraft will be located on the sea bed near where it impacted the ocean, give or take some lateral drift to a 3000m deep sea bed.

 

[Zidane98]

As for other floating debris, that could be anywhere with ocean currents now. Not much point in recovering further floating wreckage anyway, that just tells us MH370 crashed somewhere in the Indian Ocean. Which we already know.


What will tell the real story is the wreckage on the bottom of the sea floor, blackboxes (if they work) and even the remains of those onboard (quite telling if only Shah's remains found in cockpit).

Can't remember saying anything about the severity notwithstanding the fact that lithium fires involve thermal runaway.

Anyway, with regard to your comment about manual control consider the following quote from this article ...

Did lithium-ion batteries cause the loss of MH370?

Clive Irving has a lengthy article in The Daily Beast suggesting why Malaysian Airlines Flight 370 may have crashed. His starting-off point is a report that fire risk is prompting...

He asks, how, if a battery-initiated fire crippled MH 370, it could have continued flying for six hours? A fire in the forward cargo hold, he suggests, could have destroyed the power-supply line to communications and navigations systems without affecting flight controls.

He quotes Dr. Victor Ettel, an expert on the science and manufacture of lithium-ion batteries, as saying, “Even if the transponders were located in different parts of the airplane they could have been disabled by a fire in the electronics bay, instead of by a deliberate action by a pilot or a terrorist entering the electronics bay, as has been suggested. It is therefore conceivable that the electronic and navigational systems in the bay could have been disabled [by fire], leaving only the hydraulic systems working.”

This doesn't explain the fact that ACARS, all radio systems and all transpoders were disabled at the same time with no distress call from the crew.

There is no such fire that would cause 0 issues with no prior warning to the crew to all these systems going dark instantly.
