NORTHERN EUROPE (WKOW) -- Volcanic ash strikes again, causing a commotion in the skies.
Across Northern Europe, planes remained on the tarmac in Ireland, Scotland, the Netherlands and parts of the UK as the ash concentration in the air was deemed too dangerous to fly in.
The root of this chaos is the volcano in Southern Iceland that's continuing to send ash into the air that can cause a plane's engines to clog up, posing a danger to passengers.
The Civil Aviation authority took no chances, grounding flights, despite heavy criticism from airline companies.
Last month, more than 100,000 flights were canceled causing airlines to lose nearly $2 billion and leaving millions of passengers stranded.
