The easiest and safest way to make that big leap is by Tandem.
In this method, you are attached to a highly experienced instructor using a dual harness/single container parachute designed for two.
The great thing about this method is that you are never alone during your whole adventure.
Your experience begins with a short training course designed to familiarize you with the equipment, exit, body position, canopy and landing techniques. You are then matched up with your instructor who will fit you a harness designed to attach to the instructors harness.
When your name comes up on the manifest, you and your instructor will take a 20 minute scenic ride to 13,000 feet/4,000meters then freefall at 120 mph/200kph for approximately 60 seconds opening your parachute 5,000 feet above the ground.
