USA: How this year's military intelligence leaks could damage US security
WASHINGTON, April 19 (Reuters) - It was huge, expensive and top secret.
In the early 1970s the CIA built a gigantic ship called the Hughes Glomar Explorer to lift a sunken Soviet submarine from the bottom of the Pacific Ocean, according to a declassified history by the U.S. intelligence agency.
But the elaborately woven CIA cover story - that the ship was built by Howard Hughes to mine manganese nodules from the ocean depths - began to unravel with a February 1975 Los Angeles Times story, eventually forcing the agency to abandon the project.
