How do scientists uncover phenomena and explain their connections? How do engineers design machines, methods and infrastructure? At omega tau, experts give detailed answers. Over the last ten years, we have produced over 350 episodes in which we dug deeper, until we ran out of questions. Join us on our journey through the world of science and engineering: the closer you look and listen, the more interesting things get.


episode 283: The Perlan Project

Guest: Lars Bensch, Jim Payne    Host: Markus Voelter    Shownoter: Stefaan Rillaert

The Perlan Project aims to fly gliders into the stratosphere by exploiting mountain waves in order to better understand those waves and to explore the edge of what gliders can do. In fact, last September, they broke the world altitude record for gliders. In this episode we chat about the project, the airplane and the flying with engineer Lars Bensch and pilot Jim Payne.
