Let's just agree that "sense and avoid" means different things to fighter vs. heavy pilots.
These days, in the age of JHMCS/NVGs/FCR/HSD/HAD/HAS/LINK-16/SATCOM in the single-cockpit F-16, the very LAST thing a new wingman needs is another excuse to not look outside.
Also, I'm sure that - after reading "sense and avoid" (just threw up in my mouth a little), not one single pilot here said to himself: "oh...I guess that means I can also clear by using the radios, too," despite your super-awesome Tweet pattern anecdotal evidence. I've done the white jet IP thing too, and white jet drivers aren't the only dudes in the cockpit who understand how you can use your ears to aid in conflict SA. Maybe you have heard of the conventional/pop BSA pattern...
We might just have to agree to disagree on this one.
