Line 79:
A great deal of design work has been done by Greg Cole of [[Windward Performance]] to show that a sailplane for 90,000 feet is relatively straightforward, while 100,000 feet is possible, although more difficult and expensive. Windward Performance would build the sailplane of high performance pre-preg in production-quality tooling. The sailplane required relatively high-end design, analysis, and construction to be flutter-safe at very high true air speeds, and strong enough for the potentially heavy turbulence that could be encountered at 90,000 feet. It must also have well-proven, fail-safe pressurization and cabin air re-cycling systems.
In 2014, [[Airbus]] agreed to become the title sponsor, and provide sufficient funding for completion of the aircraft, flight testing and the altitude flights.
[[RDD Enterprises]], an aviation research, design and development company based in [[Redmond, Oregon]], took over the manufacture of the [[Windward Performance Perlan II|Perlan 2]].

The aircraft was completed in the summer of 2015, with first flight scheduled for 7 September. Windy conditions that day prevented the flight, which finally occurred on 23 September.<ref>[http://www.opb.org/news/article/experimental-glider-flies-for-first-time-in-redmond/ "Experimental Glider Flies for the First Time in Redmond"]</ref> Flight testing started in [[Minden, NV]] in fall and winter of 2015, using a new hangar donated by Tito.<ref>{{cite web | url=http://www.flyingmag.com/perlan-2-glider-preps-for-flight-tests | title=Perlan 2 Glider Preps for Flight Tests | date=17 December 2015 }}</ref> The first attempts to reach 90,000 feet will be launched from [[El Calafate]], [[Argentina]], deep in the south of [[Patagonia]], in the [[Southern Hemisphere]] soon afterwards in summer of 2016.<!--use month, as summer is January in South-->

The 2018 season was again based at El Calafate. The project acquired a [[Grob G 520|Grob G 520 Egrett]] turboprop aircraft for use as a tow plane. This enabled Perlan II to be towed to {{cvt|44,000|ft|0}} <ref>{{cite web|url=http://www.perlanproject.org/blog/stratospheric-tow-perlan-2-egrett|title=Stratospheric tow of Perlan 2 by Egrett}}</ref> This seems to be the highest glider tow, although such records are not registered.
