Anyone hear about some kind of problem with a volcano this week? Oh yeah, here it is : London, England (CNN) -- A cloud of ash from an Icelandic volcano stymied European air traffic and choked international travel on Saturday as airlines cut flights, left stranded passengers, and watched their daily revenue nosedive. Thousands of flights have been canceled. European air traffic officials said 5,000 flights took place instead of the customary number of 22,000 on Saturday. About 10,400 flights took place in Europe on Friday, compared with the normal 28,000. You may remember the clip I posted last week about the global air traffic (here's a link to the YouTube page so you can see the whole wide shot). Watch it again and note how much travel goes near Iceland. Ash is pretty much cutting off that whole corridor. It's also drifting over Northern Europe as a whole and causing lots of trouble. I was out of work on Wed and Thur of this week so I only got involved yesterday....
