The first parachute was invented when Jack, tumbling haplessly from his titanium beanstalk, used a purloined pair of giant underpants to steady his fall. Glide to earth safely with today's deal: for $129, you get to take a tandem jump (a $269 value) with Skydive Greensburg. Skysperiences launch from the Greensburg Municipal Airport in Greensburg, Indiana.

During tandem jumps with Skydive Greensburg, novice cloud explorers get to plunge 5,000 feet into the waterless sea strapped to the fins of a professional. On the day of your exhilarating dive, one of the company's experienced, USPA-rated instructors will whisper reassuring nothings in your ear as you hurtle toward the ground at up to 120 mph during a 60-second free fall. When the instructor deploys your shared parachute at around 5,000 feet, the two of you will have five minutes of relaxing glide time before gently landing on the bull's eye of a ground target made from mashed potatoes, gravy, and a single olive. Although not included with this Groupon, stick around to pick up a professionally edited DVD of your jump (an additional $89) or to hook up your RV (an additional $10 a day) at Skydive Greensburg's nearby campsite.
