San Miguel de Tucumán — Province of Tucumán

Official source account — 2020 annual report, printed page 20: A video from San Miguel de Tucumán showed a distant aerial feature with a double condensation trail. CIAE checked historical FlightRadar24 information for the recording time and location. It matched the feature to Aerolíneas Argentinas flight 1429, a Boeing 737 travelling from Salta toward Ezeiza at approximately 37,000 feet. The aircraft's track and twin contrails supported the agency's Type A identification. The summaries distinguish reported observations from the agency’s proposed explanations. Source Type A/B ratings describe explanatory confidence and are not encounter classes. The map uses an approximate GeoNames locality centroid, not the observation point.
