St. Louis’s Aerospace and Chemical Manufacturing Legacy
McDonnell Douglas built military and commercial aircraft in St. Louis continuously since 1939, producing fighter jets and other aircraft that used asbestos in brake assemblies, engine insulation, and fireproofing materials. Assembly line workers, mechanics, and engine testing personnel who handled these components for decades faced regular exposure.
Monsanto’s headquarters and chemical manufacturing operations used asbestos extensively in pipe insulation, reactor vessel lagging, and protective equipment throughout its St. Louis facilities. Chrysler’s Fenton assembly plants and American Car & Foundry’s rail car manufacturing added further exposure through brake linings, gaskets, and insulation used in vehicle and rail car production.
Maintenance workers, pipefitters, and production line employees across these industries represent the population at highest risk for mesothelioma from St. Louis-area exposure, particularly those employed from the 1940s through the 1980s.
Yes. McDonnell Douglas (now part of Boeing) has manufactured military and commercial aircraft in St. Louis since 1939, using asbestos in brake assemblies, engine insulation, and fireproofing materials. Missouri’s 5-year statute of limitations (Mo. Rev. Stat. § 516.120) runs from the date of mesothelioma diagnosis.
