Our launch was a failure. We used a 300g balloon that I purchased about four years ago and it burst on inflation. Lifting gas was hydrogen. Payload would have consisted of

  • SPOT tracker 
  • Byonics Tiny Tracker (Standard APRS 30 sec interval)
  • Hero 2 GoPro camera, 64 GB card, external USB battery


Balloon burst including slow motion from the GoPro camera.
