"In this adventure, The Timekeepers are whirled back in time to 1903 in Kitty Hawk, North Carolina. An exhausted Orville and Wilbur Wright are desperately trying to fix their airplane. Their initial tests had been so promising, but all of a sudden the Wright Flyer's propeller has gone missing! The Timekeepers realize it's been stolen by villainous DeLay, and only they can help save the day and put history back on track."-- Provided by publisher.
