During the early 1980s, two Boeing 747s were severely damaged by the ash clouds spewing from Galunggung Volcano on Indonesia's Java island. One of these, a British Airways flight, lost power on all four engines. While the pilots managed to restart the engines at a lower altitude, the resulting glide still ranks as one of the longest ever performed by an aircraft not specifically designed as a glider.

Another 747 encountered similar problems while flying through the ash clouds over Mt. Redbout, near Anchorage in Alaska. And at least 10 Jumbo jets and 10 DC-10s suffered multiple engine failures in 1991 from ash from Mt. Pinatubo in the Philippines.
