It sure looked to be running pretty smoothly.

I agree.

In the past I have been saved by safety glasses three times.

Each incident would have resulted in blindness.

Only a fool doesn't wear them.

That seems a curious failure. Was that the cylinder head coming off? If one
or two studs failed I'd expect the gasket to blow out and then the pressure
would be dispersed and at least some of the studs would hang on, even if
they got fairly stretched. If a rod failed, would there be enough energy in
the now-free rod and piston to knock the head off?

About 15-17 seconds into the video, you can see smoke out front, and the
engine note changes... Perhaps a piston burned through and the
turbocharger was able to stuff enough fuel into the crankcase to blow it
up from there?

You can also see the exhaust pipe distend at :14 seconds. That's where I
would have got back.

Well spotted, I guess that makes sense
