Here is an interesting graphic. The green lines indicate the projected travel of
the balloon based on several different soundings from the National Weather
Service. The red line is the travel after burst.
If you look at the different projections and see where the balloon landed the
projections are pretty darn close.
There are so many factors involved in obtaining these projections that it always
amazes me that it can come so close.. i.e., the weight of the packages, the size
of the balloon, the wind data, the burst altitude, the ascent rate, the descent
rate.
12.2 miles from predicted landing!~
Thanks to Harry (again) for running the projections for us.
