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.

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.

Northern corridor

Inconsistent with BFO sign and with African debris

Early public maps showed a northern Inmarsat ring. BFO and later debris on western Indian Ocean coasts disfavour it.

JORN not tasked the night of 7–8 March 2014

Australian over-the-horizon radar · peacetime status

Wikipedia and Australian statements: Jindalee Operational Radar Network was not operational / not tasked that night. Absence of a JORN track is not a northern-path proof.

Boeing files uninterruptible-autopilot priority

19 February 2003 · later US7142971B2

Patent architecture: remote or automatic engagement; onboard controls may be disconnected; dedicated communications; inaccessible power path. Precedent, not an MH370 installation.

Could the Inmarsat BFO have been spoofed?

Wise’s northern path stands or falls on this. Inmarsat and ATSB treat BFO as a physical Doppler residual. No public demonstration has shown a 2014-era 777 SDU emitting a false BFO while keeping a consistent BTO.

BTO range rings and BFO Doppler residuals

Inmarsat / Ashton et al. · Journal of Navigation

Burst Timing Offset describes distance from the satellite (an arc on the Earth). Burst Frequency Offset encodes relative motion and is why official analysis went south, not north.

Capt. Patrick Blelly & Jean-Luc Marchand

Independent trajectory paper

End-of-flight reconstruction used by Mentour: flame-out, APU, cross-feed, possible glide. Argues the last BFO need not be a wreck on the 7th arc.

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.

Controlled descent / ditching

Someone still flying at the end

A pilot or system flies a glide after flame-out, so the wreck lies tens of kilometres from the 7th arc. Flaperon damage is read by some independent engineers as consistent with a ditching sequence.

Flight MH370 — 17 Fascinating Facts

J. Jericho / The Free School · March 2019 · Drive backup PDF

Independent compilation of official-file facts with annexes (simulator pages, passenger list, cargo docs, Boeing patent, ACARS log). Not an official report. Several numbered “facts” are attributions that still need MOT/ATSB cross-check.

Handshake 4

21:41:24 UTC

Fourth SATCOM handshake, still on the southern corridor in BFO reconstructions.

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.

Landing MH370

Jeff Wise · Finding MH370 S1E27 · 28 November 2024 · 45:12

The northern-landing telling: discard or spoof BFO, keep BTO, fly borders, land at a long Central Asian runway (Wise’s 2015 candidate was Yubileyniy / Baikonur). Requires the African debris field to be explained away.

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.

MAGIC, Aurora and Boeing/NRL patents drop from the paper trail in 2014

Follow-up briefing: Aurora’s remote-operation work for the US military from about 2010; MAGIC and several Boeing and NRL patents then become hard to find in open documents in 2014. Redacted Blue Devil letters are shown with matching date cut-offs.

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.

Unanswered ground-to-air telephone call

18:39:52 UTC

Malaysia Airlines operations places a sat-phone call to the aircraft. The SDU acknowledges the incoming call; nobody in the cockpit answers.

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.

Last attributed radio call: “Good night Malaysian three seven zero.” Home simulator files exist; the 2018 report did not treat them as a reconstructed plan. Who was flying after IGARI is open.
