Cub Scouts

Me an my friends just got back from a cub scout meeting at a  Fire Station. It was SUPER fun! I went with my friend Palmer, Grant, Josh, Sachin, Conner, and Ella. We learned that fire fighters have an air pack but what I didn't get is, do they ever go flying up in the in the air like does the air ever go down and the person goes up and he also is like "Noooo" and the other fire fighters are like " Oh well".
