My daughter launched an Estes Spectra with booster on Saturday. D12-0 to C6-5. The pads were right in front of trees, which significantly blocked the ground wind. It appeared to be very calm. The rocket went up and arced over the trees. We recovered the booster. The chute came out above the trees, I don't know how high. We watched it drift with the stock chute until it was almost out of site. The winds aloft must have been about 30MPH, because we found it about 3300' away. Unfortunately, it landed in a newly seeded field, and we were not allowed to recover it. Spill holes in the chutes from now on!
