Post Mortem

Well, the Explorer was exactly where she said she was, in a cornfield near West Bend, WI. She was gently caught on an old corn stalk.

There was no sign of catastrophic damage or water, but it clearly didn't want to go up anymore.

I remeasured the buoyancy of the balloons at home, they are at 88 grams of lift. This compares to 109 grams originally, and a package weight of 99 grams.

So, it went too high, lost some helium, and came back down.
