FTB Chunks: Sable Aerospace

This addon fixes one of the most frustrating problems with Sable (Create Aeronautics) on multiplayer servers: Sable structures do not automatically respect land claims.

By default, moving air structures can still be used, damaged, or interfered with even when they pass through claimed territory. On a public server that quickly turns into griefing, accidental damage, and constant admin cleanup.

FTB Chunks: Sable Aerospace closes that gap.

With this addon installed, FTB Chunks protection is applied to Sable structures as well:

• players cannot freely use other players' Sable structures inside claimed chunks
• players cannot break protected Sable structures inside claimed chunks
• explosion damage is also filtered through FTB Chunks claim rules, so protected structures are not left exposed to creepers or other terrain-damaging explosions when the claim disables them

The addon also adds airspace behavior on top of basic claim protection.

When a player approaches another team's claimed territory by air, they get a predictive warning before crossing the boundary. Enter and exit messages make it clear when someone moves into or out of foreign airspace, which helps avoid accidental intrusions during flight.

There is also a configurable high-altitude free zone. By default, above Y 320 foreign claimed chunks switch to a special ruleset:

• normal use remains allowed
• block breaking is denied
• block placement is denied
• TNT ignition is denied
• airspace warnings are suppressed in that zone

The result is a much cleaner multiplayer experience:

• fewer griefing edge cases around Sable constructs
• better protection that actually follows FTB Chunks rules
• clearer airspace boundaries for players in flight
• less manual intervention for admins

If you run a server with Sable and FTB Chunks, this addon plugs a protection hole that has existed for a long time.
