Discovery

Space shuttle Discovery will take to the air on Tuesday morning (April 17), flying piggyback atop a NASA jumbo jet from Florida to Washington, D.C. to be delivered to the Smithsonian for display. Those along its flight path are in store for low passes, historic flybys and overall, quite the sky show.
The shuttle spectacle began a day early,on Monday, as the air- and- spacecraft combo was placed on full display at NASA's Kennedy Space Center in Florida. Paired with the Shuttle Carrier Aircraft (SCA), a modified-Boeing 747, Discovery was parked alongside its landing strip where the media, NASA employees and bused-in guests from the center's visitor complex were able to get one last, long look at the retired orbiter.
Even Discovery's final crew, the six astronauts who flew the shuttle's STS-133 mission in March 2011, stopped by Kennedy's Shuttle Landing Facility to bid their spacecraft a bon voyage.
