The Boeing Delta 2 rocket is fueled up during the countdown on April 19. But this first launch attempt ended in a cliffhanger three minutes before liftoff time when officials ruled there wasn't sufficient time to ensure the correct high-altitude wind data had been loaded into the rocket's guidance computer. Liftoff was scrubbed 24 hours. Credit: William G. Hartenstein
