The grand opening of The Museum of Flight‘s new Space Shuttle Trainer exhibit is set for Saturday, Nov. 10, with the Trainer ready for boarding after an 11 a.m. ceremony in the Charles Simonyi Space Gallery.

Stretching over 100 feet, and four stories high, the artifact was used by NASA to train every space shuttle astronaut. The Museum has added stairs and ramps to make the expansive cargo bay accessible to all visitors, including those with disabilities. The festive opening ceremony will be attended by officials from NASA, the Museum and Washington state. Live music and family activities will be offered at the Museum throughout the day.
