That, in turn, can be catastrophic – as the crew of two aircraft, including a British Airways Boeing 747, discovered in 1982 when they flew through an ash cloud from the Galunggung volcano in Indonesia. On both planes, all four engines stopped; they dived from 36,000ft (11km) to 12,000ft before they could restart them and make emergency landings.

That's not the only problem. Ash can pit the windscreens of the pilot's cabin, damage the fuselage and light covers, and even coat the plane so much that it becomes tail-heavy. At runways, ash creates an extra problem because takeoffs and landings will throw it into the air again – where the engines can suck it in and it will create horrific damage to moving parts that suddenly find themselves in contact.
