[p=21, 2, left]Volcanic ash can [b]clog up[/b] and damage jet engines while the [b]tiny particles[/b] of glass in the ash can also melt and block the [b]ventilation holes[/b] which can cause the engines to overheat and stop working.[/p][p=21, 2, left]The obvious risk of this happening to crowded passenger planes in British airspace was enough for the UK's [b]Civil Aviation Authority [/b]to enforce a total ban on flights – a move which was [b]mirrored[/b] by other northern European countries.[/p][p=21, 2, left]The dangers of flying through volcanic ash were demonstrated in 1982 when a British Airways flight from Malaysia to Australia lost power in all four engines after flying into a cloud of dust [b]spewed out[/b] by an eruption of Mount Galunggung in Indonesia.[/p][p=21, 2, left]After 15 minutes of [b]gliding [/b]in a [b]controlled descent [/b]from 37,000 feet (11,000 metres) to 12,000 feet (3700 metres), the pilot, Captain John Moody, managed to restart the engines once enough of the [b]molten ash[/b]in the enginessolidified and broke off. The plane went on to land safely in Perth.[/p][p=21, 2, left]Speaking to the BBC last week, Captain Moody demonstrated the typically [b]phlegmatic[/b] attitude of his profession.[/p][p=21, 2, left]"It was, yeah, a little bit frightening," he said.[/p][/size][/font][/color]
