Our 1200g Kaysam balloon burst at 5709 ft not very far from the launch site. Landing was about 50-100 ft west of the Elkhorn River to the northeast of Valley, for a flight distance of less than three miles. Had the flight ascended a few hundred feet higher, it likely would have landed in the river. This flight (unintentionally) is the shortest and lowest flown by NSTAR. Flight time was approximately 8 minutes. The balloon was about five years old, but showed no signs of improper storage when unpacked (it was purchased from eBay).
Launch conditions were a low overcast with fog and very light drizzle, but nearly 60 deg F which is quite mild for mid-November.
