There are few freedoms as liberating as being able to fly, which is why humans spent millennia inventing the airplane and why penguins are so very, very bitter. Exceed evolutionary shortcomings with today’s Groupon: for $75, you get a 30-minute discovery powered-hang-gliding lesson with an accompanying flight instructor from Paradise Air in the North Shore (a $150 value). Flights can be scheduled anytime between sunrise and 10:30 a.m.

In an open-cockpit ultra-light aircraft, a Paradise Air FAA-certified pilot teaches the passenger how to fly the agile-framed hang glider as they soar over the glistening aquamarine ocean. Paradise Air's hang-glider fleet consists of two Australian-built Airborne 912 XTs, engine-powered gliders that cradle the pilot and passenger, both strapped into two cushy seats buttressed on both sides only by blue sky. Apart from launching themselves from a trebuchet, the glider's open build allows students to experience unparalleled views of white sandy beaches and verdant O'ahu terrain. During the exhilarating flight, passengers can opt to take the controls for a hands-on experience that counts toward getting a sport pilot's license. For an additional cost not included in this Groupon, passengers can purchase souvenir photos or Blu-Ray or DVD video of their flight taken from several high-quality cameras mounted on the aircraft and a man sitting in a tree.
