When a fighter is referred to as "atmosphere capable" is that meaning that they can fight, bomb, launch missiles, etc. or does it simply mean that a ship can travel through the atmosphere? I was thinking about this cause we know there are some fighters that engage other ships in atmosphere (we see Lances, Hellcats, Excals, etc. doing it), but it would make sense that a Broadsword or Longbow could at least travel in the atmosphere to land on the surface, yet I don't think they do in Wing Commander (I might be wrong about that).
