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.
Hörnfeldt’s stated purpose is to get the underwater search restarted, not to name a perpetrator. He walks takeoff 16:41 UTC, the 17:19:30 “Good night Malaysian 370” call, IGARI at 17:20:31, and a two-step comms dropout: Mode S / TA-RA selected off about five seconds after IGARI, secondary-radar symbol gone ~37 seconds later, then an abrupt left turn. He treats a technical failure that would blank every emitter at once as a poor fit for that sequence. SATCOM: seven handshakes; first and last are aircraft-initiated log-ons, read as power interruptions; last log-on around 00:19 UTC as fuel starvation and APU/bus restore. BFO on the final log-on has been read as a very steep descent (figures up to about 14,500 ft/min appear in the independent literature) — he notes that does not by itself prove a straight dive, and cites Capt. Patrick Blelly and Jean-Luc Marchand on a possible right-engine flame-out, APU start and cross-feed. Post-radar routing is given as a turn near NILAM onto a south-westerly course that satisfies the seven arcs and stays off northern radars. WSPR (Richard Godfrey) is introduced as a possible extra trace, not as a peer-reviewed track. Sources listed in the description include the Malaysian final report and the Blelly–Marchand trajectory paper. Treat the sequential-transponder reading as a cockpit-compatible reconstruction, not as a named-pilot finding.
