Fond memories: Daily wiping off ash from the 1991 Mount Pinotubo eruption from my car with my feather duster before driving to Singapore Changi airport for flight duty.
Not a fond memory: 3 Engines quitting on a Singapore 747 from the plum of Mount Gulunggung just three weeks after Capt Moody's famous glide.
I guess its all down to the intensity of the ash. If they allow flights, I hope it only be VFR/Day.
