This mod let's you disable flying in biomes, structures and dimensions of your choosing.
Blacklisted dimensions are configured in the server config folder while blacklisted biomes and structures have to be added to the 'noflyzone:worldgen/biome/blacklist' and 'noflyzone:worldgen/structure/blacklist' tags respectively.
The mod disables anything that enables creative flight in a no-fly zone as well as jetpacks from Iron Jetpacks and the Rending Gale from Reliquary. More flying devices will be supported as they become available and are discovered.
