What's interesting is that during the "Nathan Hale" run, the team was forced to swing across the Pit and never had any contact with the ball pit at the bottom. The "Golden Pepperoni" was the first team of that production day to go down in the Pit. So whatever was the cause for the crew member being there either had to do with his job or something that happened during that run. I've been searching over archived threads on this site, and some people believe that this is evidence that Aqila was the mysterious person who had the "mishap" as described by Kirk Fogg in interview. Personally, I don't think that the crew member being in the Pit had anything to do with the players in this run, since he seems to be using either a camera or a lighting device to focus in on objects lining the Pit (possibly for segues to commercials or other shots to scatter throughout the episode?).
By the way, I have the same photo as one that was previously posted, but the outlining on the one posted covered part of the crew member, so I've uploaded mine below (photo courtesy of video posted by OlmecFan25 on youtube.com):
