Terminal velocity

I was watching this show on the this other day and i saw this episode on myth busters about a falling body. When they would drop buster from the airplane it would hurdle towards earth at a maximum speed of 120 miles per hour. This is called terminal velocity, which is the maximum speed an object falls at. This depends on mass and gravity, more mass could mean a higher terminal velocity but this is not exactly true. It also depends on the gravity too. More gravity means more force pushing on the object to go towards earth. its glad too know if i were to fall out of an airplane i could fall towards earth at a pritty cool speed of 120 miles per hour.
