After many requests and an enormous generation of interest following a post on the technology blog Gizmodo, here is the rest of the story:
This partcicular photo was taken with a film camera (to date, the last time I took an image on film) with the intent of not recoving a working camera post-launch and minimizing losses.
Knowing the forecast didn't call for rain between setup and launch time, the camera was not weather protected as is the norm, but with the hopes of doing all I could to make it withstand 1.9 million pounds of thrust, from a rocket as tall as a 24-story skyscraper, and lifting off just about 100 feet away, it was secured to the ground with three stakes and a nylon ratchet anchoring the tripod to the ground (a typical setup for a close photo: I have personally witnessed cameras thrown hundreds of feet by the fury of launches that were not properly secured).
The result on this one: a spectacular shot, a lens destroyed (though still in one piece), a camera still working and a missing trigger...
A careful search of the area finally found the sound-activated home-built trigger in the grass, stopped only by the pad's perimeter fence several hundred feet behind the camera. And yep, it still worked.
