On August 15, 2017 Airbus Perlan Mission II team gathered in the hangar for an early launch. The weather balloon team of Loris, Sandra, Stewart, Martin, Alec and Michael had collected wind, temperature, and altitude data to use to fine tune the forecast. Those hardy souls start their duties an hour ( or two) before everyone else. Since the sun was just up and the wind was blowing, it was cold out on the ramp and runway. Linda, Tago, Stewart, Alec, Loris, and Jackie were ground ops. Martin took photograghs and worked with the tail camera footage. Miguel helped with aviation translations. Sandra applied for credentials for newly arriving team members. The lower air mass was very dynamic. The Perlan 2 lost 2,000 feet on tow in the sink just before reaching the primary wave. As soon as Jim Payne and Tim Gardner got off at 10,000 feet they had 1500 feet per minute of lift. Unfortunately that quickly died back to 400 feet per minute above 14,000 feet.
