A team of German pilots from the Mountain Wave Project (MWP) and researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have achieved a groundbreaking feat around the highest mountain on Earth. For the first time, they flew to the summit of Mount Everest, 8848 metres above sea level, in a motorised glider – taking with them a special 3D camera, the Modular Airborne Camera System, or MACS. This innovative camera system, developed as part of DLR's focus on technology for security, has been designed to provide the data required to produce a remarkably precise 3D model of the Nepalese Everest region with a resolution of down to 15 centimetres. These images will help improve forecasts of landslides and floods resulting from the outbursting of glacial lakes.
