For Information only...
The Discovery Channel is scheduled to air a one hour program on the Iceland volcano incident that fouled up air travel for tens of thousands of travelers last year. My limited information is it is scheduled for 0600hrs PST on Wednesday, 16 February, 2011.
This is the same volcanic eruption that delayed and shortened or own Kelli and Zee's spring 2010 vacation to Ireland.
This post is not an endorsement, on my part, of the value of this progaram. I haven't seen it and it is widely known that the Discovery Channel has its ups and downs.
