Friends of Sarah Devereaux's family were civil engineers, so she knew from an early age that this would likely be her calling. While an undergraduate student at the Technical University of Nova Scotia, her interests transitioned from structural to environmental engineering, and she stayed to earn a Master's degree in Water Resources. She then joined Halifax office of Dillon Consulting, initially conducting construction reviews, and then transitioning into project management, starting with small projects and graduating t multimillion dollar assignments. She designed storm water systems, storm water ponds, and landfills and became the business unit manager for community infrastructures. She describes several projects, including: work for the Municipality of Guysborough, Nova Scotia; review of waste management systems for remote coastal communities in British Columbia; and resolving the "Million Dollar Hole" left at the US naval base in Argentia Newfoundland. She also volunteered with Engineers Nova Scotia, the Consulting Engineers of Nova Scotia, and eventually Engineers Canada. She has served on committees dedicated to increasing the participation of women in the engineering profession.

Dr. David Weaver describes his youthful interest in gasoline-engine powered go-karts, home-built radios, servicing cars, and how this led him to study mechanical engineering. He left his first job with the Ford Motor Company in Oakville to return to university for a Master's degree on satellites for Spar Aerospace and then a PhD in mathematics and physics. He found a university position and began researching nuclear for Ontario Hydro Research and hydroelectric power generation for Nova Scotia Power. He contributed to a model study of flood protection for the City of Venice conducted by the Dutch Hydrodynamics Laboratories in Delft. He worked on a fusion energy project the Joint European Taurus (JET) in England. In retirement, he has worked for the Canadian Nuclear Safety Commission, and with Babcock and Wilcox, Ontario Power Generation, and Atomic Energy of Canada. He talks of the evolution of computational tools from slide rules to computers and their applications to autonomous vehicles – and the importance of selecting the appropriate tool to max the complexity of a problem.

Aeronautical engineer Dr. Karl Doetsch did an apprenticeship with English Electric, an aeronautic company in the UK, before starting his university studies at Imperial College in London. Within months of starting there he worked on the development of the TSR2 aircraft, which was similar to the Avro Arrow, particularly wind tunnel testing to assess its behaviour at low speeds. He completed his PhD on supersonic aerodynamics, but the British government lost interest in the field so he joined the flight research laboratory at the National Research Council of Canada, specializing in control systems and automated control. He was responsible for the software and simulation aspects in the development of the Canadarm – which was developed between 1975 and 1981 in collaboration with Spar Aerospace, NASA, Rockwell International, and various subcontractors. He describes use of the Canadarm to repair the Hubble Space Telescope, and removing a stalactite of waste from the outside of the shuttle. He describes Canada's contribution to the International Space Station program, and the initiation of the Canadian astronaut program, where they whittled down the list of 4500 applicants to 2000, then 75, then 20, and then the final six. Part of the learning experience included addressing the physiological things that happen to people in space. The Space Station project was quite demanding politically as well as technically.
