Embedding LUA Script support to AH would enable custom features for special events, for example:
1. Enforce custom life rules (1 on aircraft, 2 in gv, if landed it is ok you can restart, etc)
2. Enforce aircraft limits in more progressive way: no more than 8 planes of type X and if damaged it is not recoverable
3. Allow conditional actions - if something is destroyed enable/disable option
4. Send messages in case of events
It could be very powerful tool for both special events and "historical arenas", it would allow implementing new features like SAR or GCI and so on.
