Molten glass found in F-16 fighter jet's engine
Text size Aa Aa

A build-up of glass has been found in the engine of a Nato F-16 fighter jet after it flew through an unidentified section of European airspace.

When volcanic ash particles are ingested into a jet engine, they accumulate and clog the fuel lines with molten glass.

The revelation, by Nato officials, adds weight to arguments that airspace restrictions should not be lifted entirely.

There is one glimmer of hope though. The drifting ash cloud is now no higher than six kilometres with much of it lower than that. Airliners fly at high altitude and theoretically could navigate
their way around or above it.

After overflying the roof of the volcano in a helicopter scientists say it is now spitting lava which suggests, “it is moving into a less explosive stage and producing not as much ash but more steam.”
