I can see a possible reason against such an idea...
In real life it took a lot longer than 90 seconds to refuel and re-arm a plane. Now you want to refuel, re-arm, add or remove ord, add or remove DTs, etc...
Considering its quicker to land, tower, grab a new plane and take back off than re-arm, the only reasons you'd want to do this are A) at a base that has no AH, and the much more likely B) you want to score w*ore.
(Score potato? hahahah)
