The ash cloud that sprouted from the Icelandic volcano Grimsvötn forced the cancellation of almost 500 flights in Europe. The affected areas are Denmark, Norway, and the southwest of Sweden. According to the European organism that controls the air traffic, the changes in the wind strength and the ash cloud will have limited effect on the flights.
Today flights of all Europe like United Kingdom, Scotland, Ireland, along with the northern countries, Germany and Denmark could also be in trouble. England had to cancel 252 flights in one day.
The risk of flying with ash in the sky can work as sandpaper with the turbines of the planes that can rip apart the internal engine mechanisms. Several other flight companies like KLM of Deutschland decide to cancel their flights as prevention.
