We saw this object in the sky from some distance away on the road to Marfa. At first I thought it was a small airplane until I realized it wasn’t moving. Then I thought it might be a hot-air balloon, except that those are usually brightly colored.
As we got closer we realized it was some sort of tethered dirigible, which seemed to be in the shape of a dolphin. As we passed it, it no longer looked like a marine mammal — just a miniature airship with a small enclosed gondola beneath it.
Since we were near Mexico, we concluded that it contained equipment for monitoring illegal border crossings — but who knows?
