Not something you normally see at the range.
This happened while my wife was visiting some co-workers in Salt Lake City. They took her and their kids to shoot some guns out in the desert. Just some shotguns and some pistols. They were visited by an Apache Helicopter. According to my wife, “you could see the gun under the nose waving at us”
Low flybys are one thing, but lingering and waving machine guns at people? Perhaps they were showing off.
In this video as the helicopter passes over the cars, you can see the gun move. But from my limited and non-existent experience with Apaches, the gun is tied to the movements of the pilot’s helmet and head.
