Shuttle countdown begins!

CAPE CANAVERAL, FL (WFLX) - The countdown begins for Saturday's planned launch of space shuttle Endeavour, but the weather forecast may not cooperate.

A stormy outlook could scrub the night launch for a third time. Last month, a leaking hydrogen line on the shuttle's external fuel tank caused NASA to scrub two launches.

Last week a fuel test showed the line had been officially fixed.
