Myro the Microlight is as mischievous, curious and prone to disaster as any other five-year old we might know! Whilst Myro loves being the Smallest Plane in the World, he doesn't like being teased about his size and being called a flying lawnmower! And when Jimo the jet fighter adds insult to injury by scaring Myro out of his own airspace, Myro gets really fed up. Myro puts his pride to one side, though, when Jimo sends out a MAYDAY call. Myro zooms to the rescue and with his eagle eyes he soon spots Jonathan suspended by his parachute over a ravine and finds the bragging Jimo crashed in the thick Australian bush. Chili the Chinook takes the embarrassed jet back to the airbase where they soon catch up with Myro, the supersonic jet fighters' hero of the day.
