Expert's Profile

Mr. Glaser helped the US Department of Justice successfully litigate a case brought against the FAA. It involved multiple technical disciplines, including airplane design, flight test, wake turbulence, and pilot human factors. His understanding of these many facets and his ability to articulate complex technical issues raised by top scientists enabled counsel to construct a clear, informed, and successful defense.
