"Secretly Jonny wants to be a jet fighter pilot one day so he's made his own jet engines to save some time. Jonny can't afford a whole aeroplane so he's had to make do with something smaller.

The jet is a 3ft long pulsejet like the one that was used on a V1 flying bomb from world war 2. It runs on propane. It glows red from end to end when it's running.

Jonny's neighbours get worried when he starts it in the garden, understandably because it's very loud...."
