According to http://www.ehow.com/list_7450870_parachutes-used-today_.html, it says that it is used today is that the military uses them to drop soldiers on the battlefield. They also used them in drag racing. The parachute used in drag racing is called a "drogue chute". The parachute helps slow down the vehicle from going really fast. It was also used by airplanes , when the airplane is about to crash the pilot pulls a red level and glids to the ground.
