    "content": "Hi Dave,\n\nThe short high altitude flights we have normally seen use a latex weather\nballoon for flight.   You put enough gas in it to get it off the ground.\nIt will rise in altitude until the balloon has expanded enough to burst and\nthen the balloon comes down usually on a parachute.\n\nThe around the world balloon flights use a different type of balloon called\na zero pressure envelope.   The material is usually mylar and the envelope\nis much bigger.   This design allows the gas to expand to fill the\nenvelope as the balloon rises in altitude while never bursting like a\nweather balloon would.   This allows the balloon to stay at whatever\naltitude it stabilizes at and just float along with the winds traveling\nlong distances at various speeds following the global wind patterns.   Very\ncool!\n\nThe same type of zero pressure envelope has been used to lift science\npayloads as well as humans to very high altitudes for extended rides.   You\ncan come down at will just by releasing the gas, you won't go back up\nthough so you have to pick a good location to bring them down to.\n\nJeff Moore  --  KE7ACY\n\n\n\nOn Fri, Dec 23, 2016 at 10:01 AM, Dave Marthouse <[email protected]>\nwrote:\n\n> I have seen posts from time to time on the BB about balloons with amateur\n> radio payloads on them.\n>\n>\n> I've got a question regarding the missions that carry payloads around the\n> world.
