Cause of death: Slow descent into the sea
This was a test flight to see how a new balloon material performed at float. Rather than floating, the balloon neared the expected elevation and immediately began a slow descent.
This test flight, along with other tests, indicates the material has an insufficient gas barrier. Aside from the material question, the GPS seems to be another that has increasingly long lock times.
