"In a 1947 fund-raising speech presented at the annual dinner at MIT, General George C. Kenney, Commander of the Strategic Air Command, speaking of future weapons systems, asserted: 'If rain could be kept from falling where it has been falling for ages,' it is conceivable that 'the nation which first learns to plot the paths of air masses accurately and learns to control the time and place of precipitation will dominate the globe.' (15) He urged MIT to look into this, suggesting a multimillion-dollar research program."
