Karl Rein-Weston has been interested in flight since childhood. At 16 he was flying a helicopter to manage game on his parent’s mountainous ranch in South Africa. While in England studying for a degree in aeronautics, Karl worked at Westland Helicopters. After receiving his Master’s degree in aeronautics and astronautics from the University of Washington in Seattle, he joined Boeing where he has been a design engineer for 747 auto flight control systems, a consulting engineer for the V22 Osprey, a programme manager for 737 and 757 avionics, a programme manager for 787 structural windows development, and a functional leader for engineering standards. He is currently supporting Systems Technology within the Boeing Research and Technology Division. He has given technical presentations at symposia and workshops in Europe, Japan, Australia and the US.

Karl is a coach and mentor for those interested in pursuing a career in engineering. His proudest contribution to the field of aviation is his daughter who will soon earn herself a Master’s degree in aerospace engineering from Delft University of Technology.

The Alan Nurick Rotorcraft Lecture takes place on 20 October 2016 at IASSA2016.
