We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Boeing 747 — The entry states the 747 was designed and manufactured between 1968 and 2023, but production ended in 2022 (the last 747 was delivered on January 31, 2023, but the production run is typically cited as 1968–2022 or 1969–2022, with final delivery in early 2023;
Concorde — The entry states 'Maximum speed=Twice the speed of sound (supercruise).' Concorde did not supercruise; it required afterburners to sustain supersonic flight.
Concorde — The entry states 'Eighteen of the twenty Concorde aircraft built survive, with two scrapped (F-BVFD and F-WTSB).' This is incorrect: F-WTSB is preserved at Le Bourget, and the two scrapped airframes are F-BVFD and F-WTSS.
Airbus A380 — Production peak is stated as 30 per year in 2012 in STATS, but later in LORE it says production peaked at 27 per year in 2012. The correct figure is 27 (30 was never achieved).
Airbus A380 — The entry says 'due to difficulties with electrical wiring, initial production was delayed by two years and development costs almost doubled' — the delay was approximately two years, but development costs more than doubled (from €9.5 billion to about €18-20 bi
Boeing 737 — The entry states the 737 reused about 60% of the 727's structure and systems, but in reality the 737 shared only about 60% of the 727's parts and systems (not structure), and it was not a derivative of the 727; it was a new design that reused some components.
Boeing 737 — The entry says the 737 was developed to supplement the Boeing 727 on short and thin routes, but the 737 was actually developed to complement the 727, not supplement it, and was intended for shorter routes where the 727 was less economical.
Airbus A320 — The A320 family overtook the Boeing 737 in total fleet size around 2019 is inaccurate; as of 2023, the 737 still had a larger total fleet size.
Airbus A320 — The A320 family overtook the Boeing 737 in total deliveries as of 2023 is inaccurate; the 737 still leads in total deliveries.
Douglas DC-3 — [staleness sweep] contains time-sensitive marker (as of 2020) - verify against current source and re-date or remove
Boeing 777 — [contradicted] The 777 is the most-built wide-body airliner. :: The source says "the world's largest twinjet and the most-built wide-body airliner." That matches, so no contradiction. Wait, check carefully: source says "Boeing 777 ... the most-built wide-body
Boeing 777 — [contradicted] The aircraft was the first commercial airliner developed entirely using computer-aided design (CAD) via CATIA software. :: The source says "The 777 was the first commercial aircraft to be developed using an entirely computer-aided design (CAD) p
de Havilland Comet — [contradicted] The Comet's design flaws included dangerous stress concentrations around square cut-outs for ADF antennas. :: The source states that square cut-outs for ADF antennas caused stress concentrations, but this is exactly what the source says, so it i
de Havilland Comet — [contradicted] None.
