The author analyzes two reports describing a now abandoned MagLev (magnetic levitation) rail system that would have run from Ontario, California, to Las Vegas, Nevada. Unlike traditional technical reports, the Budd Company Transit Division's MagLev reports appeal to utopian visions of futuristic technologies that would solve America's social and economic problems of the 1980s. The writers of these reports employ economic and political rhetoric such as risk modeling, market projections, appeals to the American dream and new frontier mentality, as well as xenophobic Japan-bashing, and downplay technical constraints on rail corridors. An analysis of these reports reveals the ethical and rhetorical dilemmas that writers face when the companies they work for seek funding for untried and untested visionary designs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

US government and industry attitudes toward mine safety and health, articulated in the instruction manuals and training guides published by the Mine Safety and Health Administration, are seen to reflect an engineering perspective based on the concept of a rational man, a perspective that undermines the ability of miners to take responsibility for their own education and ultimately obstructs effective risk management and assessment in the nation's mines. It is argued that to improve miner training and education, technical communicators must understand how underlying gendered assumptions about male rationality influence the construction of knowledge in a large government agency.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
