The article delves into a conversation between AIAA senior member Douglas Dobbin and futurist Dennis Bushnell, where Dobbin addresses inaccuracies in a previous commentary related to hydrogen embrittlement and material selection for aircraft. Dobbin clarifies that not all steels are embrittled by hydrogen, emphasizing the need for careful consideration when choosing metals. Furthermore, Dobbin highlights the complexity of contrails' impact on climate, disputing oversimplified statements about cirrus clouds' reflective properties. The dialogue escalates as Dobbin and Bushnell debate the optimal tank design for storing hydrogen on aircraft, with Dobbin advocating for cylindrical tanks while Bushnell leans towards spherical options. In a separate context, AIAA Associate Fellow emeritus Frank Hurley recalls NASA's Adaptive Maneuvering Logic program and HiMAT demonstrators, suggesting novel approaches to unmanned aircraft testing and flight control innovations. Hurley's reflections touch on the potential of advanced technologies in shaping the future of aviation. The article weaves together technical insights, historical references, and visionary ideas, emphasizing the dynamism and continuous evolution within the aerospace industry.
