Judging from the town names, this accident happened in Vermont.
Post Mills is a tiny little grass strip.

Post Mills Airport (about 10 sm north of Lebanon) used to host the
Experimental Balloon Festival, usually in May of each year. A few small
aircraft were welcome as were helicopters. The last one I went to was
in 1999. I heard an experimental balloon on a tethered flight blew up
and crashed from 50' just after we left.
