Transponder dropped in two steps, not as a single failure

Mentour Pilot and others: Mode S / TA-RA selected off seconds after IGARI; the remaining secondary-radar symbol gone ~37 seconds later; then the left turn. A total electrical failure would have blanked every emitter at once.

Secondary radar lost

17:21:13 UTC

Mode S transponder returns cease. Primary (military) radar continues to paint an unidentified westbound track consistent with MH370.

A NEW Trace! The FULL MH370 Story, so Far

Mentour Pilot · Petter Hörnfeldt · 16 March 2024 · 56:06

Type-rated 737 captain’s reconstruction from the 2018 report, Inmarsat BTO/BFO, and the Blelly–Marchand end-of-flight paper. Argues the transponder was selected off in two steps, not failed as a unit. Closes with a WSPR lead and a request to restart the search.

BD764 and BE144 — named radar feeds, and a gap after 18:02:59 UTC

Secondary ends with the transponder · primary westbound · later points still to source

The working chart labels two Malaysian Air Defence datasets: BD764 (secondary, 10-second intervals, early flight, ends 01:21 MYT with the transponder) and BE144 (primary, 10-second intervals, westbound after the turn, ends 18:02:59 UTC). The 2018 reconstruction then shows a last military return at 18:22:12 UTC after a gap. Those later points exist in the official track. Their raw source is not public.

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” still need MOT/ATSB cross-check.

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 voice contact

17:19:30 UTC · “Good night Malaysian three seven zero”

Lumpur Radar transfers MH370 to Ho Chi Minh. The reply — attributed to the captain — is the last recorded voice transmission from the flight.

Level at FL350

17:01:17 UTC

The captain reports maintaining flight level 350. The aircraft is established on the filed route toward waypoint IGARI.

The radar story and the 9 March cyberattack

Working chart · tracks, delays, and a spear-phish of the investigation

Two panels. Left: civilian secondary, Malaysian military primary, Thai paint disclosed ten days later, and the 12-hour lag before the civilian rescue centre was told. Right: one day after the loss, officials on the investigation were hit with a spear-phish that CyberSecurity Malaysia later said stole classified material toward an IP in China. Presence of a hack is confirmed as that agency’s public account. What was in the take — and whether it included radar — is still open.

Turn back across the Malay Peninsula

17:21–17:52 UTC

Primary radar shows a left turn off the Beijing airway, a crossing of Malaysia, and a track toward the Andaman Sea. The official report calls this diversion likely the result of manual inputs.

Crowd-maintained digest of the public case: 239 dead, 9M-MRO, 8 March 2014, KUL–PEK, cause undetermined. Useful as a citation map into ATSB, MOT, Inmarsat and Ocean Infinity. Not a primary source.

Communications were more likely switched off or unpowered than randomly failed

ACARS, transponder and VHF drop together near IGARI. The report favours manual off / power interrupt, without proving intent.

MH370: The Forensic Evidence

Capt. John Cox · Sit Down With Sid · 13 June 2026 · 37:10

US accident investigator. Reads the transponder drop at the FIR boundary, the southwest run to MEKAR, the northwest turn, and the 300-mile ocean leg as too many coincidences for a random failure. Preponderance, in his view: a deliberate act, high likelihood the captain.

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.

The last radio call is attributed to the captain

Official voice identification. Calm, protocol-correct handover two minutes before transponder loss.
