Red Bull Stratos Aircraft Is 55 Stories Tall, Spread Out Would Cover 40 Acres
The balloon that will take Felix Baumgartner up to 120,000 feet for his record-breaking mission is constructed of nearly transparent polyethylene strips about the same thickness as a dry cleaner bag, which are heat-sealed together. Despite the light weight of the polyethylene, Felix’s balloon weighs 3,708 pounds simply because there is so much of it (40 acres) needed to carry the Red Bull Stratos Capsule ... which weighs nearly 3,000 pounds ... aloft.
