Some disappointing news, looks like the payload never reported back after the flight, I’ve run though a bunch of scenarios in my head, among them:
- The tracking battery died before touching down, I did some pretty extensive testing, so this is not really my first thought.
- The payload landed in the Atlantic Ocean off the east coast. Looking over the initial assent reporting it looks like the balloon was rising at 600 feet per minute instead of 1000 feet per minute, this could have caused the balloon to go further east than expected, and maybe as far as the ocean.
- The payload landed in a area with no reception and could not report it’s location. Reviewing Verizon’s coverage area, it appears that just beyond and to the south of the estimated landing area, there’s a fairly large area with no coverage. I’m leaning toward this scenario.
- Some other error, the app failed, the package hit too hard or landed in water and broke the phone, I find this unlikely.
