Out and about in the desert and mountains around Las Vegas, military aircraft will fly over your head and intrude upon your solitude. However, learning to identify aircraft in flight adds an odd twist to enjoying the outdoors while hiking and birding around Las Vegas -- how many species and varieties can you identify?

B2s are so unusual that it is not hard to imagine you are seeing a UFO. One day, when one flew by quite low, I tried to take a photo but couldn't see it in the camera -- that is stealthy! When flying quietly, these huge bombers can sneak up on you, but they are capable of making huge noise. I saw one fly by low and slow in the dark with the landing lights on and the landing gear down -- through my binoculars, it looked like the underbelly of the StarWars Death Star.
