/flide and /flide2 for Elytra Flight that will launch you into the air and push you along./flide will push you at a sustained continual speed, while /flide2 will apply a slow acceleration (feels a bit more like flying a plane).Hold the sneak key (shift) at any time to end the acceleration so you can land.
