Diesel Runaway Engine

I'm aware of two incidents in our neck of the woods. Since the engine is using the lube oil in the sump as fuel, there's really no way to stop it, except maybe putting the transmission in Drive with the parking brake on and a heavy foot on the brake pedal. Maybe adding a pillow or a blanket over the air intake would help, but I'm not sure I'd want to be close to a big diesel that might blow to shrapnel any minute.

I've not done any research on the frequency of this problem, but it's one reason we went with a gasser.
