> No data with a timestamp after May 16th was found on the camera, so it is likely that none of the data recorded on the SD Card were of the accident voyage or dive.

Evidently the camera data was recorded to an external SSD card in the mission computer when the accident occurred.

The investigation team actually managed to salvage the PC as well:

Sadly it turned into a compressed ball of metal...

From the report:

> To conduct the CT scans, the large mass was evaluated by a third-party laboratory under NTSB supervision. This facility had a range of scanners with different power and energy levels and could scan large masses using a rotating table, avoiding the need to rotate the mass itself. Ultimately, the third-party laboratory attempted to image the large mass at a power as high as 320 kilovolts (kV). The scans conducted at 320 kV were not powerful enough to penetrate the object, and as a result, no internal structures or voids were visible, and no memory devices could be identified. The NTSB evaluated using another laboratory with higher power and energy CT scan devices, however, there was concern that increased CT scan energy could damage data stored on any surviving NVM chips. Consequently, higher-energy scans were not pursued.

I'm no expert, but remember reading about neutron imaging ([1]). I'm curious if that was deemed unfeasible, too expensive, or having little chance of success? From Wikipedia:

> X-rays are attenuated based on a material's density. Denser materials will stop more X-rays. With neutrons, a material's likelihood of attenuation of neutrons is not related to its density. Some light materials such as boron will absorb neutrons while hydrogen will generally scatter neutrons, and many commonly used metals allow most neutrons to pass through them.

That's a striking image! Thanks for sharing - that really hits home on the pressures involved.

Pretty sure tech exists to recover data from flash memory with cracked dies...

I guess they decided it wasn't worth pursuing.

You can just make out the heatsink fins of the three PCs there, stacked atop (and now kind of inside) each other.

That truly is one of those “let God sort them out” situations.
