Jetpacks - Only One Command

Hello! Today, I've made yet again another small creation! This time its jetpacks!

Click here for the command!

Crafting:
Jetpack - Iron Chestplate + Fire Charge
All recipes are floor crafting

Tutorial:
After putting your Jetpack on, you will see a cool model on your back! To power
your Jetpack, you are going to need coal in your inventory. Every time you jump,
if you have coal, you will fly up five blocks in the air, using up one coal. When you
run out of coal, the Jetpack won't work, so always make sure you have coal on you.
Jetpacks will also make you take no fall damage.
