From the Museum of Flight:

On Dec. 15 Santa Claus will be making his annual arrival to the Museum in a plane that might give his reindeer the shivers: it is painted like a tiger.

Santa’s Landing Party begins when his plane lands at 9:45 a.m.

The festivities continue in the galleries as Santa listens to children’s wishes while holiday music is played by the Boeing Concert Orchestra and Boeing Band until 2 p.m. Elf-trained educators will also be leading family make-and-take workshops.

Santa’s arrival is free, all activities inside of the Museum are free with admission.
