"I am," he answers, mildly surprised. "Or was, anyway, before I came here. I consulted for the Air Force."

It's a little more complicated than that, particularly when one wonders what the Air Force might want with an archaeologist and a disgraced one at that, but Daniel's primarily focused on getting them out. Or letting Melanie lead them out. She quite obviously knows the layout better than he does. But seeing as she's been so upfront about herself to him, it only seems fair that he return the favor.
