The admins will not be disabling the fly command for admins, it still serves a purpose for us. That said we will not be using it while playing the game. The only valid argument I have seen so far has been to disable it because it removes most of the challenge and fun of trying to build a jet pack. It really does take away from a several mods that we are running. This does not mean that turning fly mode off is the popular decision, we all enjoy fly mode better, that does not mean that we need to have it.
I would like us all to give the jet packs a chance.
Also, please don't assume the admins are spawning things into the game, we are not cheating, we are enjoying the game just the same as everyone else. Some people just know more about what can be made and how to make it. I am still learning so far I have only managed to make what I have seen others build. There is much we can all learn and do
