Example: Lemmy Federated Airlines Flight 360 crashes with no survivors. Now the Lemmy Federation Air Crash Investigation Bureau finds the Flight Data Recorder and Cockpit voice recorder, and they take those boxes aboard Lemmy Investigation Bureau Airfleet Flight 180 back to the investigation headquarters for analysis. This flight also crashes with no survivors. What happens now? Will the black boxes of Flight 360 still be readable? Also, what were the odds of this scenario happening?
Sorry I couldn’t sleep and had to get this question out of my head.
According to the National Safety Council there are “too few deaths to calculate odds”. (source). So, I’m pretty sure we can call the probability of two extremely-rare events happening independently in succession as near to nothing as makes no odds.
Also, modern combined units (sometimes called CVDRs) are built to withstand multiple impacts, and their storage medium is solid state. It is highly likely that, in the event of this near-impossible scenario, the recorder could be recovered again.
