CASE STUDY 2 WEATHER MODIFICATION: THE EVOLUTION OF AN R&D PROGRAM INTO A MILITARY OPERATION Federation of American Scientists "Since about 1,400 people were given access to information about the project over the six-year period, leaks appeared in the press; and in September 1971, Senator Claiborne Pell of Rhode Island as chairman of the Subcommittee on Oceans and the International Environment requested the Department of Defense to provide information with respect to the program. By December DOD had replied that the relevant chairmen of the committees of Congress with primary responsibility for the Defense Department had been informed. (...) Finally, on March 20, 1974, the Defense Department provided Senator Pell's Subcommittee with a top secret briefing on weather modification activities in Southeast Asia .... The story of rainmaking as a weapon of war became public when the top secret hearings were declassified on May 19, 1974. (65)" http://www.fas.org/man/eprint/leitenberg/weather.pdf , page 21
