Buckley Air Force Base is home to the 460th Space Wing Staff and features loads of these giant radar golf balls, which I guess are used for communicating with their “Defense Support Program” satellites.

The base also hosts the Colorado Air National Guard, who we can see here performing a rescue training exercise. It would appear that a rescueman is being lowered from a Blackhawk helicopter to the lake below, where the helicopter’s downwinds are creating circular waves.
