On 16 August1961,the 4926thTest Squadrun(Sampltig)transferred from tie Air ForceSpecialhkaponsCenter,to becomea part of Air WeatherSe~ce, MilitaryAir TransportSemnLce.

Friorto completionof the compilationof documents, interviews,and the writingof the narratives,the Russianshad startedatmospherictestingand the United Stateshad resortedtowndergroundtesting. As this historywas concluded, -. DOMINICwas underwayand the samplingstorycontinued. From the openingchaptersthe transitionis towarda ~~problem- —.. solvingllattitude.

Nevertheless,the chronicling of the cloudsamplingeffortcannotbe completelydivorcedfrom the entire nucleartestingactivities. Easically,the text containsinformationwhich all of thosedirectly associatedwith nuclearcloud samplingor with decontaminationof.aircraft shouldhave knowledge. It is hoped that a studysuch as’this will result in an increasein the underknding of the need for nuclearcloud sampling; tk-t-fiturn,will resultin an increasein the ~motivationlt . level of thosecalledupon for participationin futuresampl+ngefforts. -.
