CLEAN : Airbus backs a glider setting sights on the stratosphere

The video discusses the impact of oxygen on design, the significance of mountain waves in climate and weather, and the use of lightweight materials in high-altitude flights. It highlights the scientific research goals of understanding mountain waves, particularly in Argentina, and the application of materials like carbon fiber in aviation.

What phenomenon is expected to amplify the waves during the flight in Argentina?

What altitude is the targeted flight height for the new aircraft?
