Helicopters are constantly moving around McCarran. There are tourist rides operating seemingly around the clock so hearing a couple of helps is not a surprise. However, these two were close to each other and seemed to have a more powerful sound. It turned out that they were two USMC AH-1Z Vipers coming in to an FBO. Paul was able to try and get some shots as they landed but I had to move the car. I settled for watching them for a bit and then got the camera as they were shutting down. It was unbelievably dark given how much ambient light there is in Vegas so I was pushing the camera’s capabilities a bit. The closer one shut down first which was unfortunate but let’s not get picky. They were still there the following morning when we were shooting departures as I could see them in the background of some shots.
