We have been fairly quiet publicly, but many subsystems are coming to completion rapidly, including the helium gas overflow vent valve. Completion of anything flying on a ballon means it’s time to do some science! Tests must be done, data must be noted, hypotheses checked. Gary Flispart and I put together a detailed technical video explanation of the vacuum leak test system we’ve made.
As many on the google group know, Galen Powers and I drove a good buddy of mine, Robert Rollins to retrieve the package that was about 80 feet up in the tree. Robert owns the Louisville based business, Greenhaven Tree Care and is an arborist and expert tree climber.
Robert made it look easy, but it was a lot of work, and we appreciate all of his hard work and personal risk to get the package(s) out of the tree.
Galen took the time to document the event and put it in a slick video:
Also, thanks to Joe and Tim for finding it the first time and giving us clues to its location, and the folks from Bloomington Hackerspace for their attempts.
