Your very own set of angel wings to glide through the air like an...erm...angel!
(To fly, you must press the jump key while falling, and the elytra spread apart like a beetle's elytra. You can aim your view around to turn or adjust your pitch. Losing altitude increases speed, and gaining altitude decreases speed. Firework rockets
can be used to increase speed. Additionally, speed is quickly lost from sharp changes in direction.)
