The human obsession with flight stems from a refusal to accept limitations and an intense desire to finally move out of gravity's basement. Claim your own airspace with today's Groupon: for $139, you get a tandem free-fall skydiving excursion from Skydive Greensburg (a $279 value).

Skydive Greensburg's aerial artists chaperone their protégés two miles into the clouds to experience the graceful art of falling during exhilarating tandem skydives. Before taking to the skies to high-five weather balloons, participants meet with their instructors who present a brief training video, demonstrate jump procedures, and fit divers in jumpsuits and harnesses. One of two aircrafts then ushers guests to the jump site 13,000 feet up in the air, where tandems take their plunge and reach speeds of up to 120 mph. When parachutes deploy, jumpers feast their eyes on the Indiana countryside as they float down to the ground for a soft landing. Students are securely fastened to their instructors for the duration of the dive, and are only separated for photo ops with George Clooney–shaped clouds.

Although not included with today's deal, skydivers may also purchase a professionally edited video of their free-falling experience captured by a skydiving videographer. Excursions require no prior experience and little training, and follow a regular schedule of jump hours.

Though Skydive Greensburg sometimes features a discounted price online, this Groupon still offers the best deal available.
