Once you've found a lovely place to drop on, QUICKLY PRESS "F"! Okay, you're falling now. I hope you haven't forgotten to take your parachute?! Haha, just kidding. The parachute is automatically on your beautiful back once you get in the plane. To fall the faster as possible, you have to aim the lower as possible underneath you, and keep pressing "W". Don't stop till your parachute automatically opens. Once your parachute is open, press "W" and "D" to reach the maximum speed and land on the place you located before.
