The Gateway Aerostatic Association was formed over 30 years ago making it one of the oldest balloon organizations in the country. The goal of the GAA is to promote safe and enjoyable ballooning through education and group activities. Our membership has been graced with the presence of many pioneers of the sport including Nikki and Don Caplan, Ed Yost, and Don Piccard. Our current membership includes full-time commercial pilots, national competitors, weekend flyers, crew members, and enthusiasts. The GAA is open to all who have an interest in lighter-than-air aerostation.
