On September 12, 2018 the weather supported stratospheric wave in Patagonia Argentina. Clouds were expected in the afternoon so a 10 o'clock launch was selected. This would be another envelope expansion flight, faster not higher. On this same day we had invited many dignitaries to a presentation and unveiling of a commemorative plaque in the main airport terminal. (Blog on that to follow.) So there were representatives from Air Force, Navy, EANA, ANAC, Hyperbaric Chamber, the mayor, and all aeropuerto jefes at the airport.
