Try adding this patch（https://github.com/QuentinGruber/h1z1-server/pull/2052）, you can now see the airplane and hear the sound, but there are two new issues:
1、When calling for airdrop, players in the nearby area will immediately hear the roar of the airdrop, and this sound will not disappear with the aircraft entering and leaving. Ordinary players need to log in to the game again, and the administrator can eliminate this sound through the TP command.
2、The airdrop in the air is no longer a blue container with flashing red lights, but a vertical airdrop box.
