Good video to show how powerfull an extinguisher can be
Likely it wasn't the extinguisher that did the trick but shutting off the fuel at the pylon
With all the aeration of the nacelle after the failure and ignition, the full fire handle saves the day.
I see the fan hub laying in the inlet with all the blades seem to be missing.
Reminds me of the Anset B727 at BRS only it's the #1 engine on the 154
