As part of my trip to the US earlier this year I visited NASA’s Armstrong Flight Research Center at Edwards Air Force Base. I conducted six interviews over two days, those concerning full scale (“real”) aircraft are in this episode. We start out with Kevin Weinert, with whom we talk about the Adaptive Compliant Trailing Edge project, essentially a flap made of flexible materials to save fuel and reduce noise. Next up is Jim Less, one of NASA’s F-15 and F-18 pilots; we chat about his flying and various research projects where the jets are utilized (you can see this part as a continuation of Episode 73, where we chatted with Dick Ewers). Finally, we talk about flying the MQ-9 and RQ-4 unmanned aerial vehicles with the pilots Scott Howe and Hernan Posada.
