Simply Jetpacks

Simply Jetpacks is a mod by tonius11. It requires either Thermal Expansion 4, Ender IO or BuildCraft to loaded for much content to be added, although in the past it solely required Thermal Expansion. Simply Jetpacks adds new Jetpacks powered off of Redstone Flux (RF), or BuildCraft Fuel. These jetpacks work similarly to those of IndustrialCraft 2, but have different tiers.
