Red Sun by Volcanic Ash

The weather channels forecasted a ‘red-sun’ in the evening of 16 april 2010 en also 17 april 2010 due to Volcanic ash in the upper atmosphere, coming from the erupted Icelandic Volcano in the Eyjafjallajoekull area a few days before.

All flights in and out of the Netherlands have been suspended as ash from a volcanic eruption in Iceland moves south.

Safety body Eurocontrol said up to 4,000 flights across northern Europe had so far been affected by the cloud.The Air Traffic Control Service said no flights would be allowed in or out of the Netherlands airspace for now.
The airspace restriction was the most significant in living memory, a spokesman said.
Norway, Sweden, Finland and Denmark were among the European countries hit.
The restrictions were imposed after the Met Office warned the ash was sufficient to clog engines.
Passengers were advised to contact their carriers prior to travel.
Experts have warned that the tiny particles of rock, glass and sand contained in the ash cloud would be sufficient to jam aircraft engines.
