The CIA proprietary firm Scientific Engineering Institute was condutcting this research under a project codenamed RAINBOW. SEI Chief Engineer Dr. Franklin A. Rodgers, formerly of MIT, converted the theories of Harvard physicist Edward Purcell into systems that ,could be used on aircraft. SEI's radar-deception system consisted of a series of attachments to the U-2 .
