Rev O Matic Space Shuttle and B-747 Wind Up Toy that Works! This B 747 will auto turn around so you don't have to chase it around the house. This is very easy to assemble and disassemble. The wind up feature works great, and the Space Shuttle will shoot off with just a push of a button. This toy measures around 7 inches long. If you have any questions feel free to ask me anytime. Thanks. Box 66
