Occasionally, luck favors the prepared. This shot of the cement ship, the SS Palo Alto can be seen in the upper right corner of the photo. This shot was taken without looking through the camera lens, I held the camera up and shot continuously while the pilot rolled the airplane.
This is an example where I wanted the extra buffering of using JPEG, but the extra depth of RAW. I went with RAW knowing I probably would have enough buffer to get me through 3/4 of the roll.
