6:12am MDT - Just had a great chat with Dan McCarter and Jack Bassick of the David Clark Company, which made Felix's suit. They're here to watch the launch, too. Felix's suit is actually based on an Air Force pressure suit, McCarter tells me. Because a USAF pilot is typically in a seated position, with one arm angled to reach the throttle and the other holding the yoke, they had to redesign the suit with more mobility at the hip and shoulder joints. The exterior cover of Felix's suit also covers his entire body, including his boots, whereas the USAF cover stops at the thighs (and then the restraint layer contains the pressure). The U-2 program office is considering developing a next-gen full-pressure suit with some of these modification, McCarter says.
