Perlan 2 en Argentine

http://www.perlanproject.org/aircraft

It was a brief high altitude Argentine wave season with no good weather during expected prime time of August and September. But Airbus Perlan Mission II made the most of what weak wave was available. We learned an incredible amount about the support available in Argentina, particularly El Calafate. This final flight, on September 26, 2016, with Jim Payne and Tim Gardner was also a learning experience.
