Satellite data unit logs back on

18:25:27 UTC · Handshake 1

Three minutes after the last radar paint, the aircraft SDU sends a log-on request to Inmarsat. Investigators treat this as a power restoration to the SATCOM avionics.

Inmarsat signalling-unit logs for 9M-MRO

Perth Ground Earth Station · 7–8 March 2014

The raw-ish tables of channel, BTO, BFO and message type that underpin every arc on every search map. Released by Malaysia with Inmarsat explanatory notes.

Why Planes Vanish: The Mystery of Flight MH370

BBC · tenth-anniversary feature · WSPR

BBC anniversary piece that brought Weak Signal Propagation Reporter analysis to a general audience. Richard Godfrey’s method is not peer-reviewed; the data are not an open, reproducible track.

WSPR detections trace MH370 to ~29.1°S 99.9°E

Richard Godfrey’s latest published circle (radius 30 km, ~2,827 km²) has not been covered by an AUV launch. Earlier published points moved. Method is not peer-reviewed; the database is not independently auditable.

Can WSPR actually track MH370?

Godfrey’s circle near 29.1°S 99.9°E has not been AUV-searched. The method is unpublished in accredited journals and the database is closed. Correlation with simulator coordinates is not identification.

Did 9M-MRO have any path for external flight-control commands?

Patents prove the concept. The test is hardware/software, SATCOM/data-link, power architecture, and maintenance/modification records on this tail.

DSTG Bayesian flight-path analysis

Defence Science and Technology Group, Australia

A probabilistic reconstruction of MH370’s path from SATCOM metadata. Output is a distribution along the 7th arc, not a pin in the map.

Malaysia announces the southern Indian Ocean track

15 March 2014

Prime Minister Najib Razak states that new satellite data show MH370 flew for hours into the southern Indian Ocean. The search pivots.

Alleged thermal / wide-area video is authentic collection

Hypothesis to test — provenance not established in this desk

Circulating clips are treated as alleged. If genuine, at least one collector must satisfy geometry, band, FOV, altitude and comms. Platform IDs attached to social posts are not accepted as authority.

Aurora Flight Sciences

HALE/MALE autonomy house · Orion prime

Founded 1989. Chiron optionally piloted aircraft 1996. Global Hawk structures since 1995. Centaur optionally piloted DA42 from 2010. AACUS autonomous helicopter demo February 2014. ALIAS is later drop-in copilot work.

Captain’s home flight-simulator files

Imaged by RMP · restored coordinates mapped by commentators

Files exist. A restored route into the southern Indian Ocean has been published. The 2018 report did not treat this as a reconstructed plan.

Cubic US6641087B1 — anti-hijack remote pilot

Commercial retrofit · satellite relay · cockpit exclusion

Confirmed patent. Activation onboard or by remote override; deactivate normal pilot control; uplink airspeed/altitude/fuel; optional disable of ordinary communications; CVR/FDR upload. No installation evidence in this archive.

Deep Dive: MH370 Episode Three — The Turn Back

Deep Dive Podcast Network · 28 September 2023 · 31:12

Podcast reconstruction of the air turn-back after IGARI: military primary radar, heading 273°, altitude and speed blips the 2018 report itself flags as noisy.

External / uninterruptible autopilot on 9M-MRO

Engineering precedent exists. Installation on this airframe is not established.

Boeing US7142971B2 and Cubic US6641087B1 describe remote engagement, disconnected cockpit controls, dedicated links. No maintenance/mod/certification record currently in this archive places that architecture on 9M-MRO.

Gorgon Stare

645 AESG wide-area airborne surveillance for MQ-9

Increment 2 (ARGUS-derived EO + Exelis IR) deployed to Afghanistan in early 2014 and reached IOC. 2010 Aviation Week said it could potentially be carried on MAGIC. Organisationally adjacent; no confirmed Orion installation.

Home-simulator coordinates are not an official finding of planning

Files exist. Commentators map a southern route. The 2018 report did not convert that into premeditation.

Last ACARS transmission

17:07:29 UTC

The final Aircraft Communications Addressing and Reporting System message leaves 9M-MRO. Expected reports at 17:37 and 18:07 never arrive.

Last primary radar contact

18:22:12 UTC

The final military primary-radar return is recorded northwest of Malaysia, over the Andaman Sea approaches. After this, only the satellite terminal speaks.

Malaysian military primary-radar track

17:21–18:22 UTC · westbound after IGARI

Primary radar paints a left turn off the Beijing airway, a crossing of the peninsula, and a track up the Strait of Malacca until 18:22 UTC. Altitude/speed blip-to-blip in the file are noisier than 777 performance.

Mentour Pilot

56-minute 2024 reconstruction from the official report and independent SATCOM papers. Sequential transponder-off, seven handshakes, Blelly–Marchand end-of-flight, WSPR as a possible extra trace. Stated aim: restart the search.

Richard Godfrey

Independent · WSPR tracking

Aerospace engineer arguing Weak Signal Propagation Reporter anomalies trace MH370 to a ~2,827 km² circle near 29.1°S 99.9°E. End-points have moved. Method not peer-reviewed.

The Debris Swarm

Jeff Wise · Finding MH370 S1E19 · 15 November 2024 · 39:26

After six months with only the Réunion flaperon, a cluster of western-Indian-Ocean pieces appears in 2016. CSIRO reverse-drift and barnacle work are the scientific spine; the swarm’s timing is the puzzle Wise keeps open.

What sensors were actually on Orion by March 2014?

PB2015 says Aurora and BIG SAFARI were identifying best-of-breed GFE through FY2014. First flight had no mission system. Gorgon Stare / MTS-B / VADER remain leads, not fits.

Ham-radio SNR disturbances offered as a track · unverified

Richard Godfrey reports ~130 disturbances over the southern Indian Ocean, currently terminating in a 30 km-radius circle near 29.128°S 99.934°E. Not an official sensor. Not peer-reviewed.
