They had no idea how their own product worked. They didn’t even know it used encrypted storage. 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.
The longer I last in this world the more products I realize are the result of telling a few people who don't know what they are doing to "make it kind of work."
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…
0. They were too cheap to use an industrial grade SD. Mind boggling.
Seems like the SD card of all things performed just fine, so it hardly seems like the weak point.

It continues to amaze me how indestructible SDCards are. Until they're sold as supplemental hard drives ( cough Transcend Jetdrive cough ). Then they'll fail if you even look at them strangely.
Put one in a Raspberry pi and it will be dead in a month.
If a hardened camera can survive, I'm surprised subs don't have a floating black box that can survive an implosion and then float to the surface and begin emitting a radio signal. I guess the trick would be finding a way to securely attach the black box in a way that would ensure its release in a catastrophic disaster.
Figure 3 from the report- that's an Adafruit sensor module on a 3d printed bit of plastic with a teensy-brand microcontroller just sitting in there! Actually, the entire electronics enclosure appears printed. Very funny to see in what I assume is a million-dollar product.
What was the water condensation situation like in this submarine? Semi bare electronics sounds very very bad.

I guess he wasn’t planning for a catastrophic failure ?
He ridiculed anyone who told him he should, taking it as evidence that he was disrupting an industry. There is something slightly romantic about dying in such a way that his body turned to mist and floated away in the current. A bit like having your ashes spread at sea. With fewer steps.
Who didn't want to go and didn't feel safe, but who was pushed to come along by his father because it was his father's birthday.

The ones that aren’t accompanied by a surface ship are military, and they really don’t want anything that might automatically deploy at the wrong moment.
