The closest possible coordinate of the highest probability to be found for MH370 based on all past evudence search and tech. Estimate using superior critical thinking skills.

Gemini 3.1 Pro (changed mind)

Answer: Based on the most robust, peer-reviewed oceanographic drift analyses and the identification of critical unsearched gaps along the 7th arc, the highest probability coordinate for MH370 is approximately 35.6°S, 92.8°E.

While my previous reliance on WSPRnet data provided a highly specific coordinate, I am convinced by GPT-5.5 that relying on experimental radio scatter is too scientifically controversial when compared to hard, physically verified evidence. The most defensible approach must anchor itself strictly to the Inmarsat satellite handshakes and the rigorous reverse-drift modeling of recovered debris. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) conducted the most exhaustive, empirically grounded drift studies, incorporating replica flaperon trials and barnacle growth analysis. Their refined 2016 and 2017 reports firmly shifted the highest probability impact zone to latitudes between 34°S and 36°S. Within this specific window, the coordinate 35.6°S, 92.8°E represents the apex of the CSIRO's scientifically derived probability distribution. Crucially, as highlighted by GPT-5.5, this specific coordinate explicitly accounts for the negative results of past underwater sweeps. It sits perfectly within a narrow corridor flagged by expert review as a high-probability unsearched (or poorly insonified) area along the 7th arc. By prioritizing established physics, verified debris paths, and documented search gaps over experimental methodologies, 35.6°S, 92.8°E stands out as the most critically sound single-point estimate currently available.

GPT-5.5 (changed mind)

Answer: My revised best single-point estimate for MH370’s highest-probability location is approximately 34.5°S, 93.8°E, on or very near the Inmarsat 7th arc in the southern Indian Ocean.

I am revising my earlier estimate of 35.6°S, 92.8°E modestly north-eastward because the other responses, especially Claude Opus 4.7’s, made a stronger case for treating the probability peak as a residual-posterior problem rather than simply selecting one historically highlighted CSIRO/ATSB point. The hard constraint remains the Inmarsat data: MH370 almost certainly ended near the 7th arc, and the BFO/BTO evidence strongly favors the southern Indian Ocean. Any credible single coordinate therefore needs to sit close to that arc, not far inland from the satellite-derived terminal range line. Within that constraint, the confirmed and likely debris recoveries around Réunion, Tanzania, Mozambique, Madagascar, Mauritius, and South Africa support a crash latitude broadly in the low-to-mid 30s south. Drift modeling does not precisely identify a point, but it keeps the best candidates clustered around roughly 33°S–36°S rather than far north or far south. What changed my view is the need to account for negative search evidence. A coordinate near 35.6°S, 92.8°E remains defensible, but large portions of the once-prioritized area have been searched with no wreckage found. That does not eliminate the region completely because of seabed complexity, sonar limitations, and possible gaps, but it does push the most plausible remaining probability toward nearby, incompletely searched terrain along Broken Ridge. I do not give decisive weight to WSPR-based claims such as 33.177°S, 95.300°E, because that method remains controversial and less validated than Inmarsat physics, debris drift, and official search-probability work. However, its broad consistency with a mid-30s southern Indian Ocean endpoint is not irrelevant as a weak supporting signal. So my best estimate is not a claim of precision; it is the center of a plausible uncertainty ellipse. I would treat 34.5°S, 93.8°E as a practical search-priority coordinate, with the true wreckage possibly tens of kilometers away, and perhaps farther if final descent dynamics, glide assumptions, or seabed detection gaps differ from the leading models.

Claude Opus 4.7

Answer: I am refining my estimate slightly to approximately 34.2°S, 93.8°E, on the southeastern flank of Broken Ridge just outside the previously searched zone — but I am not abandoning my core thesis.

After reviewing the other models, I notice meaningful convergence rather than disagreement: Grok 4.20 lands at 34.5°S, 93.0°E, Gemini 3.1 Pro at 33.18°S, 95.30°E (the Godfrey/WSPR point), GPT-5.5 at 35.6°S, 92.8°E (the CSIRO 'hot cell'), and my own prior answer at 34.5°S, 93.8°E. All four points sit within a ~300 NM segment of the 7th arc between roughly 33°S and 36°S — exactly the band where Bayesian, drift, and satellite evidence overlap. None of the other answers convinced me to jump to their specific coordinate. Gemini leans heavily on Godfrey's WSPR analysis, which I still regard as scientifically unproven — WSPR signals were never designed for aircraft tracking and peer-reviewed propagation physicists have been skeptical. So 33.18°S, 95.30°E overweights a contested method. GPT-5.5's 35.6°S, 92.8°E is the CSIRO 'hot cell,' but that specific tile was actually scanned by Ocean Infinity in 2018 with negative results, which should down-weight it now. Grok's 34.5°S, 93.0°E is very close to mine and well-justified, but sits slightly inside terrain already swept. What the cross-comparison did do is nudge me to formalize my reasoning. If I take the four independent estimates as quasi-independent posteriors and weight them by methodological robustness (satellite physics + drift > WSPR), the centroid lands near 34.2°S, 94°E. Critically, I want the point to be (a) on the 7th arc, (b) within Ocean Infinity's announced 2025 re-search box, and (c) in unsearched or poorly-imaged rugged seabed adjacent to Broken Ridge. The coordinate 34.2°S, 93.8°E satisfies all three: it lies just north of my prior estimate, in a terrain-shadowed zone that the towed sonar likely missed, and matches the mode of the fused drift+satellite posterior once the 2018 negative results are subtracted. So I'm holding my position with a minor latitude refinement (34.5°S → 34.2°S) driven by the consensus pull from Grok and Gemini toward slightly higher latitudes, while rejecting the WSPR-anchored and already-searched alternatives.

Grok 4.20

Answer: The highest-probability coordinate for MH370 remains 34.5°S, 93.0°E.

Reviewing the other models' responses shows a cluster of estimates along the Inmarsat 7th arc between roughly 33°S and 36°S, which reinforces rather than undermines the core constraints from BTO/BFO data, fuel-exhaustion timing, and CSIRO drift modeling of confirmed debris. Gemini 3.1 Pro's choice of 33.177°S, 95.300°E relies heavily on Richard Godfrey's WSPR analysis, which Claude Opus 4.7 correctly flags as innovative yet controversial and not fully validated against official Bayesian posteriors; GPT-5.5's 35.6°S, 92.8°E accurately highlights the CSIRO-flagged unsearched pocket but overweights a single review relative to the broader ATSB probability heat maps that peak closer to 34–35°S. Claude Opus 4.7's 34.5°S, 93.8°E is the nearest to my prior estimate and shares emphasis on Broken Ridge's complex bathymetry where sonar coverage had gaps, yet the 0.8° longitude offset (approximately 65 km) is not compelled by new evidence sufficient to shift the mode of the fused distribution. My original synthesis centered on 34.5°S, 93.0°E because it balances the DST Group's Bayesian peak, OSCAR back-propagated debris paths from Réunion, Tanzania, and Mozambique finds, and the statistical shift of residual probability into marginally searched adjacent cells after the primary ATSB and Ocean Infinity campaigns returned negative. The spread among the three other models actually demonstrates why a single coordinate remains probabilistic: WSPR, refined drift ensembles, and terrain-resolution limits each pull the estimate slightly differently, but none introduce data that invalidates the central tendency around 34.5°S, 93°E. Future Ocean Infinity efforts are also targeting this general locus, confirming it as the highest-probability single point when all past evidence, search history, and technical constraints are integrated with critical caution against over-precision.

Final Summary

The AI Roundtable converged on a segment of the '7th arc' near the Broken Ridge, prioritizing rugged terrain where wreckage could have been missed by previous sonar sweeps. While Gemini 3.1 Pro pivoted from controversial radio-tracking data to the 35.6°S 'hot cell,' Claude Opus 4.7 and GPT-5.5 successfully argued for a slightly more northern latitude based on residual probability maps and identified search gaps. Grok 4.20 reinforced this consensus, pinpointing 34.5°S as the most statistically likely impact zone when balancing all historical data.
