You can send your second element home and you can send the other four plane flights home, but not individual. From the books I've read it was common practice to send home both members of the element if one is damaged so the other can protect them and aid in navigation. This is from pacific theater squadrons, and the distance and featureless ocean are major hazards. If there are mods available to change this I would love to get my hands on it!
