New Yorker: In the magazine earlier this month, I wrote about Greg Chung, a Chinese-American engineer at Boeing who worked on NASA’s space-shuttle program. In 2009, Chung became the first American to be convicted in a jury trial on charges of economic espionage, for passing unclassified technical documents to China.
While reporting the story, I learned a great deal about an earlier investigation involving another Chinese-American engineer, named Chi Mak, who led F.B.I. agents to Greg Chung. The Mak case, which began in 2004, was among the F.B.I.’s biggest counterintelligence investigations, involving intense surveillance that went on for more than a year.
