sami, yes the "wiggly design" is the technology that will give us mult-billions in market cap. Image the press someday if we are the first 'Strat and Back'....others have reached 65,000 but never made it back to ground. Lockheed's last airship attempt (@$200 million cost) was designed to reach 65,000 feet and never come back (they didn't have technology to bring it back down )...airship technology is very very complicated!
