Very soon, the airport is complete and the first aeroplane is sent to Sodor, but when Thomas accidentally derails some trucks, they hit a water tower, which falls and shatters on the runway, cracking it. With no other option, Thomas gathers his courage and asks the evil Diesel 10 to help them. Diesel 10 initially hesitates but relents and follows Thomas to the airport. With the aid of even Arry and Bert, Thomas collects George the steamroller to fix the runway and the aeroplane lands at last. That evening, the engines are happy to see Tidmouth Sheds rebuilt, especially Emily when she finds that an extra berth has been built for her.
