Antares Rocket Launch Scrubbed at T-12 Minutes
Oh well, it happens to the best engineers. Better luck next time. 
Having sat through a number a failed space shuttle launch attempts, I can sympathize with their disappointment.This evenings planned launch of the Orbital Sciences Antares rocket had to be canceled just 12 minutes before liftoff, due to the unexpected separation of the boosters umbilical cable while the vehicle was on the launch pad. This is the first attempt to fly the Antares rocket, which is a commercial craft and direct competitor to the SpaceX Falcon 9.
