Synopsis

Donald's top scientist, Dr. Ryan, arrives to test Chase's invention. The two of them dislike each other and don't get along. When Donald puts Dr. Ryan in charge of the space elevator, Chase immediately gets jealous. Donald then makes Chase Dr. Ryan's assistant. Dr. Ryan puts Chase in charge of screwing in the lug nuts, but Chase refuses, and Dr. Ryan builds the space elevator without Chase. The day of the launch, Chase performs a bionic scan of the elevator and finds a major braking flaw on the elevator.
