Thomas Patrick Cavanagh
Thomas Patrick Cavanaugh is an aerospace engineer who was sentenced in 1985 after being convicted of trying to sell stealth bomber secrets to the Soviet Union.
Cavanaugh was arrested at a hotel in Commerce, California, in December 1984, by FBI agents posing as Russian spies. Cavanaugh, who worked at Northrop, was debt-ridden and was "willing to take 25,000 U$S in cash for technology that cost us billions to develop".
The cloaking technology was later used in both the bomber and fighter versions of the stealth aircraft. The fighter plane saw action several years later during the first Gulf War.
