Yea, a diesel over-revving its brains is truely a frightening occasion.
The GM's (lots of Oldmobile diesels.) did this so often it was amazing.
What's really amazing is that GM never got sued for it.

I'm surprised the motor didn't hydraulic when the service manager dumped
the antifreeze water mixture. That's why we used the Halon and had a second
bottle ready if the first didn't stop the motor completely.

Long rags, don't forget the long rags. Normal shop towels could be sucked under
a valve and demolish the motor as well.

As you can tell, we had a "system" for this issue.

What this tells me is that it occurred often enough for a "most effective
way" to be discovered. :-)

We didn't have these sorts of problems when I was a boy,
back when snakes wore shoes and dirt was $2 a pound,
if you could find it. We had to make our own from rocks!

When I was in the Navy (about 50 years back) we kept a canvas bag
near the air filter to stop the engine in case of a run away.

The ones with the blower (GM 261?) were known for lube oil leaks into the air stream.
