When the server is lagging, there is a high possibility that the jetpack will send the player character into the air, which may result in death upon landing again.
This means controlled bursts of the jet pack cannot be used to safely jump from high distances, even if it slows the wearer down, severe impact damage will still apply.
The Secret Service armor and Brotherhood recon version of the jet pack does not provide fall damage reduction and does not factor in any changes of momentum.
Binding aid items that refill AP such as Nuka-Cola Quantum to a hotkey can be useful when using a jetpack, as one can refill their AP before they run out of AP to prolong the jetpack duration.
The jet pack is only available via crafting at power armor stations and armor workbenches. Mod_PowerArmor_Ultracite_Torso_Misc_JetPack Miscmod_mod_PowerArmor_T65_Torso_Misc_JetPack
