The NTSB temporarily closed public access to nearly all investigation dockets after people used a spectrogram image from a PDF in the UPS flight 2976 crash file to reconstruct approximate cockpit voice recorder audio and post it online. "We show our work and we've been doing this type of thing for years. Nobody was aware that you can recreate audio from a picture," a spokesperson for the board said. "NTSB is looking to make sure there's nothing else in the docket that could compromise anybody's privacy... now that we understand the possibility of a digital recreation." CNN reports: Cockpit voice recordings, often referred to as the CVR, capture everything commercial pilots say and are valuable during NTSB investigations, but are almost never released out of respect for the victims and their families. UPS flight 2976 crashed on November 4, when an engine separated from the wing while it was taking off from Louisville, Kentucky. The three crew members onboard were killed along with 12 people on the ground. During a two-day investigative hearing this week, the board released a docket full of details about the crash. Besides thousands of pages of reports and video showing the engine separating, it included a transcript of the CVR and a PDF file showing an analysis of the spectrogram of the audio it recorded. A spectrogram is a still image that is a visual representation of the audio, showing the ups and downs of the frequencies. Using that still image, members of the public were able to recreate the voices of the pilots in the moments before the plane crashed and post the results online. The clip, which included background noise and echoes, covered the last 30 seconds of the flight as the pilots struggled with the disabled aircraft as well as recordings of testing the NTSB did on another aircraft. In a statement on Thursday, the board made clear it "does not release cockpit voice recordings" due to federal law and because of the highly sensitive nature of what they include, but it was "aware that advances in image recognition and computational methods have enabled individuals to reconstruct approximations of cockpit voice recorder audio from sound spectrum imagery." Investigation dockets are made public for transparency, but this week, the board took the rare step of closing public access to all dockets, including the one for the UPS crash. [...] The NTSB is urging platforms like X and Reddit to remove posts with the audio.

It's the first time a major U.S. newsroom has gone on strike partly to demand protections from AI-related layoffs, according to a report from Nieman Lab. They noted that one of the picketer's signs read "Thoughts not bots," : On Wednesday, roughly 150 members of the Propublica Guild, one of the largest nonprofit newsroom unions in the country, went on a 24-hour strike. About two dozen Guild members picketed ProPublica's headquarters in New York City's Hudson Square neighborhood during working hours, as simultaneous picket lines formed in front of the publication's offices in Chicago and Washington D.C... The Guild has been negotiating its first collective bargaining agreement for two and a half years, and the one-day action was intended to put new pressure on ProPublica's management to agree to several contract proposals. The union is seeking "just cause" protections for terminations, wage increases to keep up with the rising cost of living, and contract language that would prohibit layoffs resulting from AI adoption... Beyond the strike, the ProPublica Guild has also taken its dispute over newsroom AI adoption to the National Labor Relations Board (NLRB). On Monday, the Guild filed an unfair-labor-practice charge, citing a "unilateral implementation of AI policy." The filing claims that ProPublica published AI editorial guidelines on its website last month, without first bargaining with union members over its tenets and language... A petition launched Wednesday calling for ProPublica to agree to the Guild's contract terms had received roughly 4,200 signatures by Thursday morning... Susan DeCarava, the president of The NewsGuild of New York, joined strikers in front of the ProPublica offices yesterday. During a spare moment on the picket line, she told me that while this strike may be setting precedent for her union, it likely won't be the last over AI adoption in newsrooms. "We're going to see more and more concentrated conflicts between media bosses and journalists and media workers over who has a say and how AI is used in their workplaces," she said. For one, The New York Times Guild is currently in contract negotiations after its last agreement expired in February. Already, AI language has taken center stage in the Guild's initial bargaining sessions, including over a proposal that would see Guild members receive a share of the revenue earned when their work is licensed for AI training. "Management has offered expanded severance for AI-related layoffs as a counter proposal..." according to the article.
