FAA video from the 1990s (suspected 1995) documenting hazards of volcanic ash to aviation. The video's opening recounts the harrowing KLM flight 867 of 15 December 1989, in which ash from the eruption of Redoubt Volcano caused all four of the 747's engines to fail. The aircraft ultimately landed safely.
