The trip resumed early on Thursday, with Endeavour and its carrier jet making additional flyovers - one over Tucson, Arizona, in a salute to former Congresswoman Gabrielle Giffords and her husband, Mark Kelly, the retired astronaut who commanded Endeavour's final flight on his last mission in late May 2011.
Giffords, still recuperating from a gunshot wound to the head suffered in an attempt on her life last year, watched the flyover from the roof of a Tucson parking garage with her husband and mother, according to former aide C.J. Karamargin, who joined them.
"When it came into view, Mark said, 'There's my plane!'" Karamargin recounted. "Gabby was just elated, hooting and hollering like the rest of us were."
From Arizona, Endeavour and its carrier jet flew on to California, where the spacecraft was built two decades ago, for the landing at Edwards Air Force Base.
