"April 14, 2012
— Space shuttle Discovery hit the road early Saturday (April 14) to board its jumbo jet ride to the Smithsonian.
Leaving the Kennedy Space Center's 52-story Vehicle Assembly Building at 5:00 a.m. EDT (0900 GMT), Discovery was destined for a steel gantry but not a launch pad. Rolled out before dawn, the retired spacecraft was instead headed for where it last landed from space more than a year ago.
Discovery's final flight plan will take it to Washington D.C. to go on display at the Smithsonian National Air and Space Museum's Steven F. Udvar-Hazy Center. If the weather cooperates, the air- and space-craft combo will depart Florida at just after dawn on Tuesday (April 17), touching down later that same morning at Dulles International Airport."
