Two studies were conducted in order to investigate the technical communication practices of Russian and US aerospace engineers and scientists. Both studies had the same five objectives: to solicit the opinions of aerospace engineers and scientists regarding the importance of technical communication to their professions; to determine the use and production of technical communication by aerospace engineers and scientists; to seek their views about the appropriate content of the undergraduate course in technical communication; to determine aerospace engineers' and scientists' use of libraries, technical information centers, and online databases; and to determine the use and importance of computer and information technology to them. Responses to a self-administered questionnaire that was distributed to Russian aerospace engineers and scientists at the Central Aero-Hydrodynamic Institute (TsAGI) and to their US counterparts at the NASA Ames Research Center and the NASA Langley Research Center are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
