Balls 20 (DVD)

Since 2006, altitudes at BALLS crept steadily higher. But 2011 saw a dramatic increase in high-altitude attempts, particularly in the number of flyers who were trying to attain at least 100,000 feet above the desert floor. And they reached for that altitude, and even higher, in several different types of rockets, from single stage traditional missiles, to two-stage rockets, boosted darts, and hybrids—there was even a three-stage attempt before the weekend was out.
