Thunderstorm from 30,000 feet

This photo was taken at 30,000 feet (on my flight from New Orleans, connecting to Atlanta, back to DC).  It took me a little while to realize there was a wicked thunderstorm going off in the distance.  By the time I got my camera out we were right next to it. 

I’ve never really seen a storm from the outside looking in like this before. It was pretty crazy, with lightning going off every other second at the height of it.  Hard to tell how many miles across the storm cloud was covering though. I’m glad that we weren’t in the middle of it!
