AeroBalloon, Inc. incorporates technologies used in modern yacht design to build the AB-20 balloon gondola which carries over 1000 passengers per day at Chicago's Navy Pier. The modern composite gondola is lighter than traditional steel gondolas and requires less helium to lift its total payload. AeroBalloon is led by Douglas Hase, record holding lighter than air and ultralight aviation pilot. AeroBallons have flown at stadiums and parks including New York City's Central Park, Boston Common, and Discovery Green in Houston.
The World's Largest Tethered Helium Balloon is located at Conner Prairie in Indiana.
