1st Transcontinental & 1st Trans-Atlantic Balloon Overflight- California Near Space

I’m not up on my balloon news! posted here for the purpose of completeness.  California Near Space  was already slashdotted four days ago.

Amazing, they beat the White Star team and Robert Rochte, who threwdown on transatlantic ballooning earlier in the year with his SDG-10, which appears to still be grounded.

White Star’s not working with off the shelf balloons though– they’ve got a bigger goal: DIY  tropospheric superpressure balloons.  these will be capable of multi-week flights, if successfully built.  Dan Bowen’s talk– Jump to 3:30 into this talk, and see the superpressure tetroon discussion.  5:40, discussion of Rochte’s designs.
