Though humans could always fall, the invention of the airplane paired falling with other enjoyable activities such as watching movies, eating hot meals, and not landing in the middle of the ocean. Explore the history of machine-aided leaps with today's Groupon: for $18, you get admission for two and two MaxFlight Simulator rides at EAA AirVenture Museum (a $31.50 value if redeemed before Memorial Day, a $37 value beginning Memorial Day).

EAA AirVenture Museum exhibits more than 20,000 aviation artifacts and approximately 225 aircraft spanning the colorful history of human flight. Visitors can fulfill needs for imagined speed by gazing upon WWII-era fighter planes such as the majestic Spitfire or the muscular F-51D Mustang, inspired by the engineer's deep friendship with Pegasus. Specimens such as the skeletal Fike Model C and the appropriately named Stits Sky Baby, built in 1952 to be the world's smallest airplane, represent more experimental chapters in aviation history. Today's Groupon also includes a ride for two in a MaxFlight simulator that swings and rolls as it responds to complex stunts and aerial maneuvers.

Museum admission also grants access to the neighboring Pioneer Airport, a to-scale replica of a 1930s transportation hub complete with functioning aircraft and heated debates between Roosevelt and Hoover supporters. Before visiting the museum, it's a good idea to go on the virtual tour and plan a route through the 180,000-square-foot carnival of aero-knowledge.
