Space Shuttle Endeavour: NASA to Fly It Over Tucson to Honor Gabby Giffords HOUSTON (updated) - The space shuttle Endeavour is on a 2,700 mile cross-country trip - so you had to wonder if it couldn't make one small detour. It is to go on permanent display at the California Science Center. Mark Kelly's request for Endeavour to make a detour and fly over Tucson, so Giffords could see it one last time, wouldn't take it that far out of the way, especially when the idea was for it to be seen anyhow. The last-minute suggestion was a bit of a surprise to NASA, but late in the day it put out a statement saying it would honor Kelly's request. "As part of the delivery of Endeavour to Los Angeles, Endeavour will be flown over the city of Tucson," said the agency. NASA decided to honor that request to pay our respects to a long-time agency supporter in former Rep. Gabrielle Giffords and Kelly, who commanded Endeavour's final mission, STS-134. The flight over Tucson will add no additional time or cost to the delivery of Endeavour.
