Bodies are mostly water, which is not compressible. So not really. But all the voids would have filled very quickly: the sinuses, ears, trachea, and lungs would have collapsed instantly. The bodies would also have been "pasted" against the opposite bulkhead to the failure, as unlike water the air around them would have been very compressible indeed.
Milliseconds, at most.
Not that anyone had to die.
I'll watch the drone footage of the deep ocean, thanks.
If it was structurally compromised, the implosion would be so fast, a combustion event a la what happens in diesel engines would have occurred.
There would be no bodies. There would only be shreds of pressure hull.
The titanium hemispheres may have maintained their shape. There is a slight chance it may have been a pinhole leak, and someone had a second to go "Uh..." before the rest of the structure started giving way.
It is clear that even these "strain gauges and microphones" to detect compromise of the structure were useless, or that the issure ultimately rested on the window in the front.
The main point to keep in mind is that short of finding the two hemispheres in the next day or so, we'll likely not know the full details with regard to the course of events of the unmaking of the vehicle.
The Sea has claimed them, and she is wont to give up her dead. Hubris, met by the cold hard edge of reality, has proven to be an insufficient aegis once again.
May they rest in peace.
Implying the middle carbon fiber imploded.
