Editing Advanced Soaring Concepts Apex (section)

== Project status ==

Initially scheduled for flight tests in 1998, the Apex project faced multiple delays due to technical challenges. By January 1999, the aircraft was under construction, with delivery to NASA's Dryden Flight Research Center anticipated in March or April. However, the project was mothballed before completion.<ref name="NASA_Apex" />

The program saw a brief revival in 2000 but was ultimately canceled. Subsequent high-altitude research objectives were achieved through other NASA projects, such as the [[AeroVironment Helios Prototype|Helios]] [[solar-powered aircraft]], which reached altitudes exceeding 96,000 feet (29,260 meters) in 2001.<ref name="NASA_Apex" />
