Excellent flight to a very high altitude. (launched from Mark Thell's tower); Unfortunately, I waited till I left the launch site to pick it up as it had drifted about 1/4 mile away but next to the road. I threw it in car, but didn't remove engine right away. Engine swelled due to sitting on wet turf for an hour, and the rocket was destroyed trying to get engine out of mount 2 months later...
