No. They have a ground avoidance alarm but not an air-to-air warning, after all, when you dogfight you are very close to the other aircraft and under some circumstances you come nose-to-nose during the merge and in the fur-ball.
The jet is hardly a billion dollars.
Line of sight is an issue for ALL pilots and is likely what is involved here.
If anything, the F-16 is larger and can be seen easier than the C-152. And if you are “showing your wife or kids how you can fly” means you are not paying attention.
Situational awareness is key.
Let the mishap board figure out what happened.
Comments from people that hardly can tell (if at all) why an aircraft flies, let alone understand the concepts of tactical flying and leisure flying, is not useful.
Airplanes can fly, it’s the helicopters that are questionable.
Does an F16 have a radar?
