This shot was the perfect case of being at the right place at the right time. I happened to have a window seat looking the right way with the cleanest airplane window I have ever seen, and I had my camera on me, shooting away at the incredible clouds that we were flying past.
I only did a B&W conversion and some level adjusting, but otherwise this is nearly untouched.
Thanks all for the comments and interest, I do appreciate it!!
Note: I uploaded a new version at the end of 2014, I started over on the conversion process as the first one done in 2005 was slightly outdated...
