Probably you saw this video of mine where a NPC rides a MMU/jetpack and is not suffocating.


(sorry for my sloppy English)

This is how I did that:

0) Back up your world.
1) Install NBTEdit mod.
2) Use the command /nbtedit on a NPC
3) Disable "damag"e or enable "invincibility" (you have to search the flag/variable, I don't remember, it was MC 1.7.10, bear me. Ask if you have troubles finding it)
4) Save.

NPC is now invincible. Yeah, that's an all or nothing thing.
