Yup,I remember seeing a documentary about that incident.Another one I forgot to mention was a British Airways 747 that,some time in the early 1980's,had all 4 engines shut down after having flown through volcanic ash...which caused the engines to seize up.I remember seeing a report that passengers were kneeling in the aisles praying during that crisis.
I was flying in the states when Mt Saint Helen’s erupted and spewed ash.
Lots of reports of severe engine damage from the ash. Thing is, the reported damage was hyped and pictures of the damage were mostly nonsense.
Pitting happens but out-and-out engine failure and component failure makes a good story.
Then when Iceland had their eruption a few years back, many of the photos from jets flying during St Helen’s were re-cycled.
We flew and the most we encountered was pitting, not catastrophic component failure.
