Special Signal is a magazine story.
Thomas takes the children to see an air show, but on the way home Thomas breaks down. The children remember how the jets had made shapes with their colourful vapour trails. They lay in a nearby field spelling out the word 'HELP' in big letters. Harold, who is flying about on patrol, spots it and rushes to get Donald and Douglas.
- The performing jets are based on the famous "Red Arrows" and "Blue Angels".
- Annie and Clarabel do not have their names on their sides.
