Simply Jetpacks Mod (1.18.2, 1.1.5) adds jetpacks that allow you to fly. It is an addon EnderIO. Redstone Flux powers the jetpacks.
Other than these changes, the core features of the jetpacks remained the same. Jetpacks are still tier-based, and higher tiers still offer extra functionality such as the emergency hover mode, which prevents players from falling to their deaths, or the charger module, which charges any armor pieces or tools that the player has in his or her inventory. There are two types of jetpacks: an “armored” version and a non-armored one. While the armored jetpack provides greater protection, it does have the disadvantage of a higher energy cost when hit by hostile mobs or players.
