Neigh?

Neigh?

It's a solid piece of silicon encased in epoxy, so there's nothing really to get crushed. Contrast this to something like a cellphone that's made of hundreds of separate parts and has void space that will get crushed.

This comment made me wonder how much easier proximity fuzes would have been to develop in WW2 had they had transistors (or integrated circuits). I assume making modern solid state electronics 20,000g shock resistant is much easier than doing the same to vacuum tubes.
I see a lot of discussion in this thread stemming from some confusion+not reading the actual report[0]. Some key points: 1. The Camera+Card was encased in a separate enclosure made of titanium+sapphire, and did not seem to be exposed to extreme pressures. 2. The encryption was done via a variant of LUKS/dm-crypt, with the key stored on the NVRAM of a chip (Edited; not in TrustZone). 3. The recovery was done by transp…
If the encryption was that easy to bypass, was it worth it at all?
The NTSB's original report has more detail on how the SD Card was encrypted and how the NTSB managed to decrypt it: https://data.ntsb.gov/Docket/Document/docBLOB?ID=18741602&Fi...
Does not leave SubC in a particularly flattering light...
This was either outsourced or done by some junior engineer who was putting pieces together like it was another Raspberry Pi project that just needed to kind of work.

When was the last time your phone stopped working due mechanical PCB damage? Typically the limiting factor on your phone is the screen breaking, your battery life getting too short, wear and tear on components like buttons or the charging port, and factory defects. Epoxy isn't going to help with any of those. The only thing it would help with is exposure to water, but if other parts of your phone like your screen are…

It wasn't in the crushed part, it was in the camera's shell, and the camera was mounted outside, if I understood properly.
The picture looks like the camera + storage SD card were in a sealed metal tube that was untouched.
