Two girls and two boys were standing in the middle of Lychford Green airfield. The airfield wasn't used any more and its buildings were in ruins. Grass grew on the broken runways.

A black shape was falling out of the dark clouds. 'It's a World War Two Spitfire!' Tom shouted. 'And it's going to crash!'
