When using the jetpack in normal mode(not hover), you will die when landing from a short fall of 1m(block) if you, during any part of your flight, went high enough that the fall would kill you. Mekanism-1.10.2-9.2.0.292

I can reproduce this as well.

I can also reproduce this. Was super annoyed when it first happened 😄

Appears to be fixed in 1.11.
