I was on an early morning commuter flight from Santa Barbara to LAX in 1999 or 2000 and saw a beautiful sunrise worthy of a photograph. My gear was stowed in the overhead bin and I could have gotten it out, but didn't want to cause a problem for the person seated next to me. I enjoyed the scene and let it go and have regretted it since. In September this year I was flying from Atlanta to Orlando and saw a beautiful sunset worthy of a photograph so I shot it with my iPhone. My gear, a D800 and various other stuff, was stowed in the overhead bin. Oh how I wish I'd gotten it out.
Here's the iPhone photo.
