The Finnish air force has released images showing the effects of volcanic dust ingestion from inside the engines of a Boeing F-18 Hornet fighter. Five of the air force’s Hornets were involved in a training exercise on the morning of 15 April, just hours before the imposition of airspace restrictions due to the ash cloud spreading from a major volcanic eruption in Iceland.
One aircraft’s engines have been inspected so far using a boroscope, with melted ash clearly visible on its inside surface. The air force decided to release the images to show the potentially damaging effects of current flight activities, says chief information officer Joni Malkamäki in a press release.
