This is about the alleged "UFO" video. However, I'm not interested in speculation about what exactly the aircraft being tracked in the video is.
What is "autotrack" in an F/A-18 Super Hornet? Does it involve tracking by the radar, infrared, or digital interpretation of the video stream by a computer?
I've provided a link to the video. This shows the aircraft (the alleged "UFO") being "tracked" by what the pilot claims to be "autotrack":
As a bonus question, what is the other pilot asking about? He asks "Did you box a moving target?", what does it mean to "box" a moving target? Does it refer to radar tracking?
