AI is being used to resurrect the voices of dead pilots
Original reporting by TechCrunch

In a chilling demonstration of artificial intelligence’s rapidly advancing capabilities, the National Transportation Safety Board (NTSB) recently halted public access to its comprehensive accident docket system. The drastic measure came after the agency discovered that AI tools had been used to recreate the voices of pilots killed in a UPS plane crash last year, with these synthetic audio clips subsequently circulating online. This incident underscores a profound new challenge for agencies tasked with public transparency and data dissemination, as technological progress outpaces existing legal and ethical frameworks.
Federal law explicitly forbids the NTSB from including sensitive cockpit audio recordings in its publicly accessible investigation dockets. However, the online accident file for UPS Flight 2976 inadvertently provided the raw material for this digital resurrection. It contained a spectrogram file, which converts sound signals into visual data. A popular YouTuber first highlighted the theoretical possibility of reconstructing audio from such an image.
The reconstruction revealed
That theory quickly became reality. Individuals, leveraging both the publicly available transcript and sophisticated AI tools like Codex, successfully approximated the cockpit voice recorder audio. In response, the NTSB swiftly restored much of its docket system, but critically, 42 investigations remain closed for further review — including the file pertaining to Flight 2976. This episode serves as a powerful reminder of AI’s dual nature, offering both investigative promise and unprecedented risks to privacy and the integrity of sensitive information.
The National Transportation Safety Board's recent decision to temporarily withdraw access to its public docket system marks a pivotal moment in the ongoing dialogue concerning data accessibility, artificial intelligence capabilities, and ethical responsibility. What initially appeared to be a technical oversight – the inclusion of a spectrogram file in an accident docket – rapidly escalated into a profound breach of privacy when readily available AI tools were employed to reconstruct the voices of deceased pilots. This incident unequivocally demonstrates the unprecedented power of generative AI to transform seemingly innocuous or anonymized data into deeply sensitive, high-fidelity personal information, thereby challenging long-held assumptions about data security and the true implications of "publicly available" content.
