The capsule was buried at the same time as an oak tree sapling, part of the celebrations of the 80th anniversary of Manchester Airport. Ten saplings were given to Knutsford Town Council by the airport.

The letter says: “To whoever opens our time capsule – our children have spoken about what sort of world they would like to see in the future and how the world could change. We all hope everyone in the future is happy and kind to each other. We hope our worries about climate change, war in foreign lands, reduction of habitat for wildlife, Brexit and much more have been solved. Many of the children wonder if Manchester United will ever be as good as they used to be, and if Manchester City will still be winning the league. The children wonder what sort of games will be played – will children still play on PlayStation/Xbox, or will there be something else? Will children still go to school or will they learn at home via the internet and all have their own headset and a robot that teaches them? The children think we will not have cars and will have our own electric bike or scooter to get around Knutsford.”
