Headed right over me while I was out for a walk on the frozen lake...
Flying low over a white, frozen lake at high noon provided for some good reflected light on the bottom of the C-17:

As (bad) luck would have it, I only had my AF-S 35mm f/1.8G with me. Its fantastic sharpness allowed for the 100% crop in the photo above, though.
I like this shot but was disappointed that I didn't get a good sun star from the 35mm f/1.8G at f/8.
