Be on the lookout for BTS-1Y, a high-altitude balloon payload. Purple line is a predicted flight path. Light blue is what we have of the actual path. Green is Dan (KK4DAN) driving around looking for it, and dark blue is a short bit of Brian (WX4BK), Blake (N4BWR), and I when we were still beaconing. The various pins are different predicted landing sites. The two red are from the same source, but one assumes an 800 foot per minute ascent rate and the other is 500 FPM
