I tried to explain the reason for the disappearing logo—the disparate data sets and how sometimes our client software didn’t call back to our servers for a new image. In those rare cases, his logo might not load because EarthViewer did not know that the image being viewed was from Airphoto USA. We only showed his logo when looking at one of his photos. “Desperate databases?” he asked. “No, disparate,” I said, “as in different.” “Why don’t you just fucking say different?”
