I was making a farm and was digging some dirt with my shovel and whenever the dirt dropped, I couldn't get it into my inventory, it was just stuck on the ground. Then, I started glitching through the dirt kind of like I was flying with my elytra. I then used my elytra and it was like I couldn't stop flying after using a firework. For about 30 seconds I was just flying at a really high speed as if I was constantly using my rockets to propel me.
