Hot Air Balloon: Economic Crisis Style
Cluster ballooning is beautiful in its simplicity. The pilot is harnessed to a bunch of helium-filled balloons, each of which is tiny compared to a standard hot air balloon. Control doesn’t come easy. Without the vents used by hot air balloons for altitude control, cluster balloons rise almost uncontrollably, leaving the balloonist to burst or cut balloons loose to level off or descend.[Karl Fabricius of Environmental Graffiti]
