Mayday

Mayday is a fire truck in Planes and Planes: Fire & Rescue.

Planes
In Planes, Mayday is first seen taking fuel from Chug. He then leaves just before the delivery truck carrying Roper arrives in Propwash Junction. Later, Mayday cheers after Chug tells him and some other citizens that Dusty Crophopper is in the Wings Around the Globe.

At the end, he is seen in the crowd celebrating Dusty's victory.

Planes: Fire & Rescue
In Planes: Fire & Rescue Mayday starts off by switching off the fire near the Propwash Junction Airport. Ryker didn't understand that it's not his only plan so he almost closed the airport until Dusty became a firefighter for him. In the credits, he is seen visiting Cad Spinner in the death valley and allying him.
