From the Museum of Flight web site, "Come and see Master Builders Bob Jacobsen and Cole Horton with their beautiful R2 units R2-D2 and R2-M5. Learn about some of the robot movie making and special effects from the Star Wars universe and what it took to build these amazing replicas, sometime from the Droids themselves! Are they really fusion powered? How much do they weigh? How do they travel to the Museum? All of your questions will be answered. Fun and informative for all ages. There will time to meet the builders and get pictures with the Droids afterward in this all new presentation."
