Jim Yungel and Bill Krabill were instrumental in my grasping the enormous role the NASA Wallops Flight Facility team played in fostering core technologies of the airborne laser scanning business. Jim also had a couple of vintage photos to share. The Airborne Oceanographic Lidar lives on today as the Airborne Topographic Mapper.


My visit to the Toronto area to visit Allan Carswell included a swing through Teledyne Optech, where Paul LaRocque showed me around in October 2017.


I didn’t make it to Antarctica in August 2017, except via Skype, but Xinzhao Chu shared a few photos.


Not far from Xinzhao Chu’s office at CIRES in Boulder, Matt Hayman of NCAR showed me around his and colleague Scott Spuler’s lab in July 2017.
