MH370, On-again, off-again search

AI Thread Summary
The search for Malaysia Airlines flight MH370 has been suspended by Ocean Infinity, as confirmed by Malaysia's transport minister, due to unfavorable seasonal conditions. This renewed search, which began in February 2025, followed the Malaysian government's approval for Ocean Infinity to utilize advanced marine robotics in the search efforts. Discussions highlight the complexities of locating the aircraft in the deep ocean, with some participants expressing skepticism about the likelihood of finding any remains, given the aircraft's presumed descent into the ocean. There is speculation about the aircraft's breakup and the potential for significant debris to be concentrated in one area. The conversation also touches on the technological advancements in tracking aircraft engines, noting that many modern engines are equipped with GPS and satellite reporting systems, which could enhance future search efforts. The effectiveness of these technologies and the need for innovative monitoring systems are emphasized as critical factors in the ongoing search for MH370.

I was watching a video about a renewed search for the remains of MH370. It apparently started in February 2025, but is now apparently suspended.

Search for Malaysia's long missing MH370 suspended

The latest search for Malaysia Airlines flight MH370 has been suspended by maritime exploration firm Ocean Infinity as it is "not the season", Kuala Lumpur's transport minister said. The plane went missing more then a decade ago.

Back in March 2025 -
KUALA LUMPUR, Malaysia (AP) — Malaysia’s government has given final approval for a Texas-based marine robotics company to renew the search for Malaysia Airlines Flight 370, which is believed to have crashed in the southern Indian Ocean more than a decade ago.

The video, which covers some technologies used to define the search regions, and some mention of Ocean Infinity's capabilities. The narrator is MenTour Pilot (Petter Hörnfeldt).



The use of SATCOM and the anomalies caused by aircraft flying through the atmosphere is interesting.

The findings at East African coastlines suggest that the aircraft broke apart, likely while diving into the ocean. I used to think of such a search as a search on land because I better imagine it. So how likely is it that you find some parts of an aircraft somewhere in the USA, or even anywhere in NM? And now add a couple of kilometers of water depth. I consider this a fruitless approach and would be really surprised if they could find anything.

I don't think it was a dive into the ocean, so much as a descent onto the ocean. That would explain why it was control surfaces that broke away, rather than internal parts from a debris field. I expect the engines were torn off, and sank, and that the bulk of the aircraft is in one place, with seats and cargo remaining within the fractured fuselage.

It is easy to give up, if you don't know what to look for, or the capabilities of the instrumentation. If MH370 is in the search area, I would expect it to be found.

The wrecks of two small ships were found during the earlier search for MH370. The wrecks of two trawlers sunk in the late 20th century were also discovered.
That demonstrates the range and resolution of the systems employed.

Maybe somebody who has a lot of satellites in the sky pre-armed with surface-facing telescopes could start some kind monitoring and tracking system.

*edit: Not sure if telescopes for visual would even be necessary until there's a problem, maybe some other kind of sensing or signal analysis could work to detect problems?

I think you will find that the leased engines now have GPS location and a satellite reporting system to the owner/manufacturer and insurer. The engine reporting communications will be independent of the aircraft systems.

Hmm, I'm not sure of the context here. Was MH370's engine not leased?
*I see. It was not. So I guess, what about non-leased engines then?

I have no idea how to interpret your post.

The majority of jet engines are now leased, but they will all call home to log data. That data should now include the GPS location.

MH370 was powered by two Rolls-Royce Trent 892 engines. Data from these engines was transmitted to the Rolls-Royce monitoring centre in the UK before the plane disappeared. I believe that was done as short data packets, via Inmarsat, geostationary over the Indian Ocean.

It should be more secure if the engines use their own independent power and satellite links, not the aircraft's communication systems.
