Thor Odden, stranded in Rome

Flight in schedules in Europe were almost back to normal today, but that doesn't really address the tens of thousands of flights that were canceled over the past week after the spread of volcanic ash from Iceland.

Experts predict it could take days -- even more than a week -- to clear a backlog of stranded passengers. Among those is Thor Ole Odden, a St. Olaf College student who is stranded in Rome.
