NTSB Wants PDF Removed After It Exposed Final Cockpit Audio From UPS Crash

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.
