Because I only weighed 500 pounds in this system, we could do it with a balloon that was five times smaller than that, and that allowed us to use a launch system that was dramatically simpler than what needs to be done for a much larger balloon.
私の場合はたったの200kgですから ５分の１の大きさの気球で済みます ですから 大きな気球が必要なシステムよりも 打ち上げシステムが 遥かにシンプルになります
