This might be my own ignorance, but I do not see a way to achieve sustained flight, even as an Airbender. No matter what i do, I am unable in increase altitude in-flight.

Exactly what I had wondered, one of the builds that I had used a while back had a feature of where you were able to glide throughout the air with ease but I wondered what had happened to it after?

Somehow I got the Master Glider to effectively function as a self propelled object, with steering that only worked in 3rd player view like a Elytra. I have sofar been unable to repeat the incident.

Edit: I found..something.

BUG
Air Jump (higher teirs) can be chain-fired to generate a small amount of lift per jump. Equipping a glider actually disables the cooldown of the ability. However, there appears to be a memory leak (or something?) in the Air Jump/Glider, as after a few hundred jumps while flying, they began locking my computer up every time I used it.

Edit: Cannot repeat memory drain. Now suspecting it was related to the recent Windows & Java Update, which has since been patched.

Memory drain is probably a combination of java + me not properly managing modified abilities when using a glider.
