A former Canadian defense minister, worried about pollution of the atmosphere by fossil-fuel emissions, has asked governments around the world to stop hoarding their secret alien technologies and use them to stem global warming. "We need to persuade governments to come clean on what they know," Paul Hellyer, 83, told theOttawa Citizen. "Some of us suspect they know quite a lot, and it might be enough to save our planet if applied quickly enough." Presumably, the advanced technology, gleaned from captured UFOs, would help airplanes to fly with less pollution, and maybe save money, too. Hellyer has told the press in the past that he believes UFOs are real visitors from other planets, and also that he believes President Bush wants to send men to the moon so they can build a military base in case aliens threaten the earth.
