Gas ballooning is the ultimate challenge for balloonists: they fly higher and farther than hot air balloons, often exposing pilots to violent weather conditions. Each year, the Balloon Fiesta hosts the America's Challenge Gas Balloon Race, which began in 1995. This competition, based entirely on the distance traveled by a balloon, is the premier gas ballooning event in the United States. Over the years, Albuquerque has hosted additional hot air balloon festivals including two gas balloon World Championships and two editions of the Coupe Aéronautique Gordon Bennett, the world's oldest and most prestigious gas balloon competition.
The most unusual and exciting feature of this famous New Mexico hot air balloon festival is that spectators are allowed to walk amongst the balloons as they inflate on the launch field each morning. Visitors are welcome to ask questions and meet the pilots--they may even be asked to help out a crew member with the inflation process! When it is time for a balloon to launch, "zebras" (the traffic directors dressed in black and white outfits) will clear a path in the crowd for each balloon to take off.
