Gabrielle Giffords is determined to return to Florida to watch her astronaut husband lead the final launch of the space shuttle Endeavour. A spokesman for the Arizona Representative said on Monday that his boss is just awaiting word on when the flight will be rescheduled. Miss Giffords had travelled from Houston to Cape Canaveral to watch the launch, which was scheduled for last Friday but was delayed because of a technical problem. The launch is off until at least Sunday. Giffords returned to the Houston rehab hospital where she’s being treated after being shot in the head while meeting constituents.
