My stealth bomber is damaged, but it has no "fortify until healed" option and just letting it pass a turn without performing any action does not cause it to increase in HP.
Is there a way to heal the stealth bomber, and if there is, how is it done?
EDIT This question is now obsolete. From the latest patch (April 2011 patch, version 18.104.22.1685) notes:
Units: Add “Fortify until Healed” option for aircraft. Before, they only healed when inactive, which could cause confusion for the player.
