Spaceblimp-4 made it up to 103k feet and
back down in one piece!
See http://wiki.hacdc.org/index.php/HacDC_Spaceblimp_4 for details. (Spoiler: it was cool!)
Join us on the spaceblimp mailing list if you’re interested (http://hacdc.org/cgi-bin/mailman/listinfo/spaceblimp).
As we work through the photos and data, expect to see more fun stuff emerge.
