It's all what you want to do. Personally, I like bringing the birds back home, but there is a big kick in the pants punching 'em out of sight, too.
Sun in the eyes, sun covering up the tracking smoke, max roc alt, engine choice, and/or a reco failure all of these, and more contribute to a MIA. A roc like your BBII may disappear, even on maiden flight. Don't let that get you down if it happens. Stand up, salute it bye-bye, and go home to build another one, or better yet, launch what you have left. It takes the edge off losing one.
Uh, Fatboy, paint that thing any color you want. it's big enough to spot, and the wide BT keeps it very low.
You gotta get out there and FLY.
TRUST ME, I AM CONTINUING TO LEARN THINGS. That's part of the fun, too.
