"On 8 November the NTSB published the list of what investigators have recovered from the Learjet 60 N722BD crash in Greenacres, Florida: both engines, parts of both wings, the flight deck, the tail. One thing isn't on it: the cockpit voice recorder. This update walks through the dig, what a recovered engine can and can't tell investigators, the recorder rules for a jet like this, what happened to another Learjet's recorder in Philadelphia, and what the internet is arguing about, kept separate from what the NTSB has actually said.".
