The eruption of Iceland's Eyjafjallajökull volcano intensifies on April 14, 2010, sending a massive ash plume into the atmosphere, posing a significant danger to Jet aircraft engines and causing the largest closure of airspace in Europe since World War II, disrupting travel for millions of passengers and cargo flights for more than a week.
