The Airplane plant has no toggle for loopback and strafe modes, meaning that on applicable aircraft these must be set manually after building them rather than being able to set them automatically. I believe this needs two changes:
LuaRules/Gadgets/unit_tactical_ai.lua (for setting applicable units)
LuaUI/Widgets/unit_start_state.lua (for start states and behavior)
As far as I can find, these are the two main things that would need adjusted.
