How Volcanic Ash Can Kill An Airplane

As volcanic ash spreads from an eruption under a glacier in the Eyjafjallajokull region of Iceland, the British have taken the drastic step of locking down the country’s airspace.
Here’s why.

The world’s bustling air traffic corridors pass over hundreds of volcanoes just like the one in Iceland ? all of which are capable of sudden, explosive eruptions of fire and ash. In the United States alone, aircraft carry many thousands of passengers and millions of dollars of cargo over volcanoes each day. As we see today, volcanic ash can be a serious hazard to aviation even thousands of miles from an eruption. Airborne ash can diminish visibility, damage flight control systems, and most importantly, cause jet engines to fail.
In fact, according to Boeing public relations officials, in the past 30 years, more than 90 jet-powered commercial airplanes have encountered clouds of volcanic ash and suffered damage as a result.
