There ' s only been a lack of evidence given to the public . High ranking government officials have disclosed the information before but it just didn ' t stick apparently . If the main stream media showed quotes that ' s military officials and other important people have said then it would ' ve been disclosed by now . I just posted this quote on another post but here it is againLet there be no doubt . Alien technology harvested from the infamous saucer crash in Roswell , N . Mex . , in July 1947 led directly to the development of the integrated circuit chip , laser and fibre optic technologies , particle beams , electromagnetic propulsion systems , depleted uranium projectiles , stealth capabilities , and many others . How do I know ? I was in charge ! I think the kids on this planet are wise to the truth , and I think we ought to give it to them . I think they deserve it . Colonel Philip Corso , Former head of the Foreign Technology Desk for United States Army Research and Development , National Security Council member , Eisenhower Administration .
