General Thoughts / Observations
This was a mystery flight. I expected the balloon to float at 30,000 feet, it never exceeded 5,500 feet. If floated for 19 hours before the signals stopped.
While flying, this balloon had impressive tower signals. There was one signal with 47 reporters! The signals reached as far away as Australia, Antarctica, Africa, South America, and Europe.
Thoughts for next time
I am going to repeat the test with a bit more free lift (6 versus 3.5 grams), maybe that will help understand why MM48 did not float higher.
