Too large and specific a request sorry I don't have time and this is not something I want add. This plugin has a native "F18_ShowAirstrike" to create the Airstrike, you could create a small 3rd part plugin for such things.
Prototype Grenades allows throwing a Molotov to trigger and Airstrike.
You can use Command Overrides to set the flag for this plugins "sm_strikes" command and give your friends that flag to allow them access.
