WHY ASIA-PACIFIC

A third of the world’s air-travel-kilometers fly here. Half the next decade’s growth lands here too.

Asia-Pacific carriers handled 33.5%IATA 2024 of global passenger-kilometers in 2024, ahead of Europe (26.7%) and North America (22.9%). International RPK grew +26.0% year-over-year and IATA forecasts another +9% in 2025 — 52% of all industry growth, nearly half of every new air-travel kilometer the world will add.

Boeing’s 20-year commercial-market outlook puts 19,620 new airplanesBoeing CMO 2024 — roughly 45% of global demand — into Asia-Pacific and China. China alone moved 741M passengers in 2024. Taipei Taoyuan handled 44.7M and ranks #13 globallyACI 2024 for international traffic. Hong Kong ↔ Taipei is the busiest international city pair on earthOAG 2024.

The fact that gets buried: over 70% of aviation incidents involve voice-communication failureNASA ASRS · EUROCONTROL. Between the failure and the consequence sits an 11–18 second intervention window — the exact layer FlightRadar24 and airport SMR can’t see. The 2024 JAL516 / Tokyo Haneda crash (5 dead), the LaGuardia Air Canada / fire-truck collision (2 pilots dead), and Tenerife — all rooted in radio, not in radar.

The US has NASA ASRS (2 million event reports since 1976). Europe has EUROCONTROL Safety Data. Asia-Pacific carries 40% of global commercial traffic, and has no equivalent. Meanwhile the regional accident rate climbed from 0.92 to 1.04 per million sectors (2023 → 2024), and only 53%IATA Safety Report 2024 of those investigations are completed — among the lowest finish rates of any region.

A third of the world’s air-travel-kilometers fly through Asia-Pacific airspace. Half the next decade’s growth lands here. Only half of its accident investigations get finished — and the root cause of 70% of incidents lives in a voice layer no one was watching.

ASIA-PACIFIC IN VIEW

Looking ahead at Asia-Pacific.

Asia-Pacific is the world’s biggest single air-travel market, and the fastest growing — a third of global passenger-kilometres, and nearly half of the next decade’s new-aircraft demand both land here. Hong Kong ↔ Taipei is the busiest international city pair on earth. We start at three Taiwan hubs; the next 11 are where the receiver network extends. The track scrolls slowly leftward; hover to pause.

The platform

Research that publishes,
operations that scale.

Three layers. Antennas pick up every transmission, AI reads and classifies it in 1.65 seconds, public surfaces ship it as citable evidence. Every component is named below — every API documented, every model under a permissive licence, on our own hardware.

Surface

Where every transmission becomes citable, queryable, replayable.

CI28: A Complete Record of an Uninvestigated Event

On 2 November 2019, an unidentified man climbed into the main gear bay of China Airlines CI28 at Taipei Taoyuan; the crew of Asiana 712, holding behind, spotted him and called Taipei Tower. The event falls outside TTSB's safety-investigation mandate, and no standalone CAA bulletin was issued — so no official report exists. In its absence, four minutes of tower audio plus press coverage are the only widely-circulated public record. This piece archives that material in an indexed, citable, traceable structure — as an example of how an uninvestigated event can still be fully recorded.

CI202: Nineteen Days of Silence — How the Public Saw the Truth First

On 14 June 2020, a China Airlines A330 landed at Taipei Songshan with all three primary flight-control computers failing near-simultaneously; manual braking stopped the aircraft 9 metres from the runway end. Public reporting appeared 19 days later; the TTSB final report took 15 months. Inside that gap, public data was scarce in kind. This piece argues why ATC tower audio reached the public record faster than the investigation did, and what its specific place is among ADS-B, NOTAM, and DFDR.

How we got here

Six years of receivers running.

The platform you see today started as a 16-year-old recording an event no one else had on file. It’s still that — running 24/7, archiving everything, in case it matters later.

Origin2019-11

CI28 — a stowaway, no investigation report

A man climbed into the landing-gear bay of an A330 at Taipei Taoyuan. No TTSB inquiry, no civil-aviation bulletin. The 4-minute tower recording on a 16-year-old’s YouTube channel ended up the only public record. The channel was hungATC.

Validation2020-06

CI202 — 19-day media gap, 9-metre stop

Three flight-control computers failed near-simultaneously on a Taipei Songshan landing. The aircraft stopped 9 metres short of EMAS. 19 days of silence, then nine outlets independently cited the hungATC capture. The TTSB report — 15 months later — corroborated every tower-observable fact.

Audience2023

5,380 subscribers · 686k views · 7 outlets

A continuous archive of every major Taiwan aviation event since 2019, monetised through nothing — just running. Media stopped emailing for permission and started naming the channel as a source.

Now2026

Three runways, 17 anomaly classes, 1.65s end-to-end

Whisper-V3 + Gemma 4 mature; NVIDIA GB10 makes local inference viable. The hobbyist receiver becomes a platform: 326-hour APAC corpus, hungASR + hungNLP on owned hardware, 22 public APIs, deployed in 53 seconds.

Next2027–2028+

Federation across APAC

Y1: full Taiwan coverage + first paying education contract. Y2: Hong Kong + Singapore federation. Y3+: airport-grade in-place deployments — sovereign AI for ANSPs and operators who can’t send audio off-site.
