>> president ronald reagan speaking in 1987, confessing, essentially, to selling weapons to iran, even though he says his heart just still couldn't believe that he did it. before that, it was president jimmy carter speaking in 1980. and again, not good news. >> late yesterday, i canceled a carefully planned operation which was under way in iran to position our rescue team for later withdrawal of american hostages who have been held captive there since november 4th. equipment failure and the rescue helicopters made it necessary to end the mission. as our team was withdrawing after my order to do so, two of our american aircraft collided on the ground following a refueling operation in a remote desert location in iran. >> president jimmy carter
