-- Reduced airbreak penalty severity
-- gave glider limited durability.
-- Improved gravity adjustment function.
--- Changed airbreaking process
+-- Changed airbreaking process
-- Removed airbreak penalty, as any 'advantage' seems minimal after new adjustments
-- Removed airbreak until minetest devs are smart enough to implement better serverside players.
-- Simplified liquid check.
+-- Modifications by gpcf
+-- 2018-12-09
+-- get shot down while flying over protected areas marked as no-fly-zones (flak, from German Flugabwehrkanone)
+-- set these areas with the /area_flak command
+
+-- Modifications by SpaghettiToastBook
+-- 2018-12-29
+-- Physics overrides use player_monoids mod if available
