So... what happened?

So... what happened?
Iceland is located on the Mid-Atlantic Ridge.
The North-American and Eurasian plates move apart- called constructive plates.
This causes magma to rise to the surface and form volcanoes.
The latest eruption occurred under a glacier.
The water cooled the lava quickly resulting in glass particles entering the plume.

Why can’t we fly?- Which are true?
The particles erode the fans of the engines.
Glass in the plume melts and coats the internal parts of the engine.
The aircraft is likely to be hit by lava.
The particles can sandblast the windscreen making it difficult to land.
Ash blocks the ventilation system, causing the engines to overheat and shut down.
Gases from the volcano could cause the pilots to pass out.

Ash can add significant weight to the aircraft and change its balance.
Ash can cause damage to instruments that measure pressure and airspeed.
Pilots are unable to navigate due to the poor visibility.
