General Thoughts / Observations
General Thoughts / Observations
One of the best slow and steady ascents, the balloon reached 15,230 feet then started a slow descent with a final water landing in Gasparilla Sound.
The seal at the balloon neck may not have been adequate.
Thoughts for next time
Thoughts for next time
Stick with low free lift.
Seal balloon hole prior to folding.
